Low Complexity Parity Check Code for Futuristic Wireless Networks Applications

Low-density Parity-check Codes for Wireless Relay Networks

In wireless networks, it has always been a challenge to satisfy high traffic throughput demands, due to limited spectrum resources. In past decades, various techniques, including cooperative communications, have been developed to achieve higher communication rates. This thesis addresses the challenges imposed by cooperative wireless networks, in particular focusing on practical code constructio...

Parallel Sigma-Delta ADC Structures Density Parity Check Code Decoders and Low Complexity Techniques for Low

In this thesis, contributions are made in the area of receivers for wireless communication standards. The thesis consists of two parts, focusing on implementations of forward error correction using low-density parity-check (LDPC) codes, and highbandwidth analog-to-digital converters (ADC) using sigma-delta modulators. LDPC codes have received wide-spread attention since 1995 as practical capaci...

Low Complexity Techniques for Low Density Parity Check Code Decoders and Parallel Sigma-Delta ADC Structures

Complexity-Optimized Low-Density Parity-Check Codes

Using a numerical approach, tradeoffs between code rate and decoding complexity are studied for long-block-length irregular low-density parity-check codes decoded using the sum-product algorithm under the usual parallel-update messagepassing schedule. The channel is an additive white Gaussian noise channel and the modulation format is binary antipodal signalling, although the methodology can be...

Performance Analysis of High Efficiency Low Density Parity-check Code Decoder for Low Power Applications

In this study, we propose a low power, high efficient Low Density Parity-Check Code (LDPC) Decoder Architecture for error detection and correction applications. LDPC codes have been adopted in latest wireless standards such as satellite and mobile communications since they possess superior error-detecting and correcting capabilities. As technology scales, memory devices become larger and more p...
