We evaluate the performance of downlink multiuser relay networks (MRNs) equipped with a single amplify-and-forward (AaF) relay. A thorough and exact analysis is conducted to analyze the outage probability of MRNs under dissimilar Nakagami-m fading conditions. More specifically, we derive new closed-form expressions for the outage probability and the probability density function (pdf) of the highes... View full abstract»

• ### Improving Achievable Rates in MPSK Amplify-and-Forward Relay Networks via Clipping

Publication Year: 2010, Page(s):2133 - 2137
Cited by:  Papers (5)
| | PDF (588 KB) | HTML

Companding techniques, which are conventionally considered to reduce the peak-to-average power ratio (PAPR) for orthogonal frequency-division-multiplexing (OFDM) systems, decrease the achievable rate. However, we propose to employ clipping, one of the companding techniques, to improve the achievable rates for M-ary phase-shift-keying (MPSK) amplify-and-forward (AF) cooperative communications in th...

• ### Joint Opportunistic Subchannel and Power Scheduling for Relay-Based OFDMA Networks With Scheduling at Relay Stations

Publication Year: 2010, Page(s):2138 - 2148
Cited by:  Papers (24)
| | PDF (754 KB) | HTML

In this paper, we study a joint opportunistic subchannel and power-scheduling problem in relay-based orthogonal frequency-division multiple-access (OFDMA) networks. In most previous works on relay-based networks, immediate relaying at relay stations (RSs) without allowing opportunistic scheduling at RSs was considered. Under this strategy, each RS should transmit the received data from the base st... View full abstract»

| | PDF (344 KB) | HTML

Relay selection is crucial in improving the performance of wireless cooperative networks. Most previous works for relay selection use the current observed channel conditions to make the relay-selection decision for the subsequent frame. However, this memoryless channel assumption is often not realistic given the time-varying nature of some mobile environments. In this paper, we consider fin... View full abstract»

Analytically studying the outage performance of channel-state-information (CSI)-assisted amplify-and-forward (AF) cooperative networks with maximal ratio combining (MRC) receivers at the destination has always been a difficult task. In this paper, we will derive upper and lower performance bounds - including outage probability, ergodic achievable rate, and average symbol error rate - for such a ne... View full abstract»

This paper studies a relaying technique based on the signal-to-noise (SNR) threshold in cooperative networks using hierarchical modulation. Hierarchical modulation is useful in applications that require different protection classes of the information. In particular, a cooperative network with one source, one relay, and one destination is considered. Two different protection classes are modulated b... View full abstract»

Network coding has been known as a spectrally efficient technique in wireless networks. However, when it is applied to a two-way relay channel (TWRC), it suffers from performance degradation caused by the asymmetric position of the relay. In this paper, we suggest remedying this problem by using hierarchical modulation at the source node. We investigate how hierarchical modulation can be incorpora... View full abstract»

| | PDF (948 KB) | HTML

The IEEE 802.16j standard has been developed to provide performance enhancement to the existing IEEE 802.16e network by incorporating the multihop relay (MR) technology. However, frequent handoffs and low spectrum-utilization issues that were not encountered in IEEE 802.16e may be incurred in IEEE 802.16j. The relay station (RS) grouping is one optional mechanism in the IEEE 802.16j MR standard to... View full abstract»

Multiple-input-multiple-output (MIMO) wireless channel models are often too simplistic to accurately model wireless propagation effects or too complex and/or site specific to be used for analytical purposes. In this paper, we develop a double-directional MIMO channel model that accounts for important propagation effects like scattering, clustering, and channel depolarization and antenna effects li...

Foliage is a rich scattering environment that is slowly time varying. Most previous investigations in foliage models center on the statistical modeling of clutters and targets. Ideally, it would be desirable to characterize the nature of the propagation channel in foliage; however, it has not been investigated in detail up until now. This paper studies the problem of nonline-of-sight (NLOS) channe... View full abstract»

We propose and parameterize an empirical model of the outdoor-to-indoor and indoor-to-indoor distributed (cooperative) radio channel, using experimental data in the 2.4-GHz band. In addition to the well-known physical effects of path loss, shadowing, and fading, we include several new aspects in our model that are specific to multiuser distributed channels: 1) correlated shadowing between differen...

• ### Directional Sound for Long-Distance Auditory Warnings From a Highway Construction Work Zone

Publication Year: 2010, Page(s):2266 - 2276

Directional sound can be used to provide warnings to specific vehicles without disturbing other vehicles on the highway. An example of such an application is the need to alert a vehicle that is likely to intrude into a highway construction work zone. Long-distance auditory warnings potentially reduce the time for the driver to visually locate the work zone. This paper reviews the currently availab... View full abstract»

The derivation of the equivalent circuit for a single-sided linear induction motor (SLIM) is not straightforward, particularly if it includes longitudinal end effects from the cut-open primary magnetic path, transversal edge effects from the differing widths between the primary lamination and secondary sheet, and half-filled primary slots. This paper proposes an improved series equivalent circuit ... View full abstract»

Auto rickshaws are three-wheeled vehicles that are extensively used in many Asian countries as taxis of people and goods. Although the vehicle design is well suited to the environment in which it operates, it is a crude and inefficient design. Due to poor vehicle maintenance and the use of inefficient two- or four-stroke engines with very little pollution control, auto rickshaws present a grave po... View full abstract»

We consider a differentially encoded phase-shift keying (DPSK) signal that is transmitted over a channel affected by correlated Rayleigh fading. For this problem, we derive the exact maximum a posteriori (MAP) symbol-detection algorithm. By analyzing its properties, we demonstrate that it can be implemented by a forward-backward estimator of the channel, followed by symbol-by-symbol complet... View full abstract»

We recently proposed the dynamic spectrum leasing (DSL) paradigm for dynamic spectrum access in cognitive radio networks. In this paper, we formalize this concept by developing a general game-theoretic framework for the DSL and by carefully identifying requirements for the coexistence of primary and secondary systems via spectrum leasing. In contrast to hierarchical spectrum access, spectrum owner... View full abstract»

Bit-loaded orthogonal frequency-division multiplexing (OFDM) with convolutional coding is a powerful technique for transmission over quasi-static frequency-selective fading channels. Further enhancements in data rate are achieved by combining loaded OFDM with multiple-input-multiple-output (MIMO) transmission. Motivated by the lack of appropriate error-rate analysis techniques for this popular typ... View full abstract»
