• ### Two-Dimensional Error-Pattern-Correcting Codes

Publication Year: 2015, Page(s):2725 - 2740
| | PDF (1033 KB) | HTML

Two-dimensional (2D) cyclic codes are presented which correct any single occurrence of known 2D error patterns within a 2D array of bits. Applications for this type of codes include storage and display devices. The code construction begins with a generation of distinct syndrome sets for all targeted 2D error patterns. A method to refine the syndrome sets is then presented for making each syndrome ... View full abstract»

• ### New Scalable Decoder Architectures for Reed–Solomon Codes

Publication Year: 2015, Page(s):2741 - 2761

In this paper, we devise new scalable decoder architectures for Reed-Solomon (RS) codes, comprising three parts: error-only decoding, error-erasure decoding, and their decoding for singly extended RS codes. New error-only decoders are devised through algorithmic transformations of the inversionless Berlekamp-Massey algorithm (IBMA). We first generalize the Horiguchi-Koetter formula to evaluate err...

This paper proposes a novel alternative to the Logarithmic Bahl-Cocke-Jelinek-Raviv (Log-BCJR) algorithm for turbo decoding, yielding significantly improved processing throughput and latency. While the Log-BCJR processes turbo-encoded bits in a serial forwards-backwards manner, the proposed algorithm operates in a fully-parallel manner, processing all bits in both components of the turbo code at t...

Differential encoding (DE) is a classical technique at the transmitter that allows simple noncoherent detection at the receiver. On the other hand, trellis-coded modulation (TCM) is a bandwidth efficient technique which offers reliable data transmission. In this paper, we aim to find the best concatenation order of TCM and DE for channel phase coherence over N=2 symbols. Besides the well-known TCM... View full abstract»

• ### Erasure Floor Analysis of Distributed LT Codes

| | PDF (1153 KB) | HTML

We investigate the erasure floor performance of distributed Luby transform (DLT) codes for transmission within a multi-source, single-relay, and single-destination erasure-link network. In general, Luby transform (LT) codes exhibit a high erasure floor due to poor minimum-distance properties, which can be improved by maximizing the minimum variable-node degree. The same behavior is observed for DL... View full abstract»

This paper addresses the problem of designing low-density parity check decoders robust to transient errors introduced by faulty hardware. We assume that the faulty hardware introduces errors during the message-passing updates, and we propose a general framework for the definition of the message update faulty functions. Within this framework, we define symmetry conditions for the faulty functions a... View full abstract»

In this paper, we study two-way satellite relaying between two earth stations (ESs) willing to exchange their signals via a satellite. The satellite communication has big problems of propagation delay and fast channel gain fluctuations, due to which it is difficult to generate perfect channel information in ESs for self interference cancellation and decoding of transmitted symbols. Therefore, the ... View full abstract»

Relaying is an emerging technique for 3G/4G high bandwidth networks in order to improve the capacity of edge nodes. As the deployment cost is high, there might be a few number of relay nodes in the cell which can help the edge nodes to transmit their data. From this perspective, one of the key problems in a relay equipped node is to make decision which edge nodes to be helped and how much power ne... View full abstract»

| | PDF (1841 KB) | HTML

Relay selection is a simple technique that achieves spatial diversity in cooperative relay networks. Generally, relay selection algorithms require channel state information (CSI) feedback from all cooperating relays to make a selection decision. This requirement poses two important challenges, which are often neglected in the literature. Firstly, the fed back channel information is usually corrupt... View full abstract»

Radio-frequency (RF) impairments, which intimately exist in wireless communication systems, can severely limit the performance of multiple-input-multiple-output (MIMO) systems. Although we can resort to compensation schemes to mitigate some of these impairments, a certain amount of residual impairments always persists. In this paper, we consider a training-based point-to-point MIMO system with res... View full abstract»

We investigate the sum-rate-optimal precoding for the uplink of the multi-cell large-scale MIMO systems. Specifically, we focus on transmitter precoder design based only on the statistical channel state information (CSI).

In this paper, we propose a hypothesis testing based sequential frame synchronization technique that is robust against fluctuations and imperfect estimation of channel gain at the receiver. The proposed detector uses division in the decision rule to cancel the effect of channel gain, and therefore is called division based hypothesis testing (DHT). We show that the receiver operating characteristic... View full abstract»

With the increase of cell density and explosive growth of data traffic, user centric is becoming one of the design principles of next-generation cellular networks. One meaning of user centric lies in that no matter where a user is located, its demand in quality of service (QoS) will be guaranteed in high probability. One approach to achieve such an ambitious goal is allowing each user to select se... View full abstract»
