    Full-duplex transmission is a promising technique to enhance the capacity of communication systems. In this paper, we investigate two-way amplify-and-forward (AF) relay systems in the full-duplex scenario. Compared with the traditional half-duplex AF relaying, the full-duplex system uses only a single phase to complete the two-way or bidirectional transmission and has the potential to achieve high...

    In decode-and-forward cooperative networks, the best relay node is often selected among many available nodes to provide the diversity gain. Decentralized selection mechanisms such as timer-based relay selection are commonly used to achieve sub-optimal performance with low overhead. In this paper, we focus on the spectral efficiency of both centralized and decentralized relay-selection schemes. The... View full abstract»

The outage probability is adopted as the optimization criterion and a relay location optimization problem is formulated. Analytical and numerical results are provided to show the advantages of the location optimization. The intriguing effect of residual self-interference (RSI) introdu... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (237 KB) | HTML iconHTML

    This paper considers a relay network where sources communicate with the receiver via relays under frequency-selective fading channels. A spreading sequence design scheme, which is subjected to maximizing the signal-to-interference-plus-noise ratio (SINR) is proposed. It is shown through simulations that a better bit error rate (BER) can be achieved using this proposed scheme. The sensitivity of th... View full abstract»

    This paper proposes a soft-output detection algorithm based on multi-hop-return sphere searching for distributed space-frequency coded cooperative communication system over frequency-selective fading channels. The algorithm finds out the vector point of the sphere center through the sphere decoding quickly at first, and then returns to collecting soft decoding information layer by layer. Theoretic...

    Modulation detection is important to many communication and electronic warfare applications. In this paper, we propose a hierarchical blind modulation classification algorithm for underwater acoustic communication signals. Due to the complex environment encountered by underwater acoustic communication, the cyclostationary features of such signals are significantly different from those of their rad...

    Blind modulation classification is an important aspect of today's military systems and is projected to play equal important role in future cognitive radio systems. Modulation classification in MIMO systems present the added difficulty of having to deal with a set of mixed signals as they are received at the receiving antenna array. Whereas, in narrowband SISO systems, the channel was assumed to be... View full abstract»

    Automatic modulation classification (AMC) is an important component in cognitive radio and many efforts have been made to improve the AMC's successful classification rate, especially when the environment is noisy. The cyclic feature has excellent resiliency to noise, so it has been frequently adopted as the feature for AMC. In this paper, in order to enhance the reliability of the system, we propo...

    This paper solves the problem of Automatic Modulation Classification (AMC) without the knowledge of some key signal parameters. The main achievement is the estimation of signal centroids in a non-cooperative environment. The estimation is based on an approximate distribution theory and implemented with automatic constellation grid segmentation. The classification decision is made by finding the mo...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4631 KB) | HTML iconHTML

    A geolocation approach applicable to multipath environments is considered that leverages map data and differential delays from channel impulse responses measured at one or more receiver locations. Measurements are made at one or more receiver sites without requirements for time synchronization. The approach requires knowledge of the receiver locations and plan-view map data that includes 2D outlin... View full abstract»

    Batch-mode maximum likelihood (ML) received signal strength (RSS) emitter geolocation algorithms produce location estimates from a block of data collected over an observation period using either a single sensor or collected at one time instant by multiple spatially dispersed sensors. Due to practical constraints such as processor speed, memory for data storage, time for data transfer and communica... View full abstract»

  • Non-data-aided Joint Estimation of Time and Frequency Offset in OFDM Systems Using Channel Order Based Regression

    Publication Year: 2013, Page(s):73 - 77
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (199 KB) | HTML iconHTML

    Previously proposed non-data-aided time delay and carrier frequency offset estimators typically require multiple orthogonal frequency division multiplexing (OFDM) symbols to achieve good estimation performance, which is not well-suited for positioning, navigation, and timing (PNT) applications in which fast acquisition time is critical. In this paper, a novel non-data-aided joint time and frequenc... View full abstract»

    We consider the problem of data detection in the absence of channel state, symbol timing and noise power information. We propose a system parameter estimation method based on a two-step implementation of the Expectation-Maximization (EM) algorithm. Due to the sampling time offset, the received sequence is correlated. As a result the EM algorithm cannot be directly implemented. We divide the receiv... View full abstract»
