Performance Analysis of Protograph-based LDPC Codes with Spatial Diversity
In wireless communications, spatial diversity techniques, such as space-time block code (STBC) and single-input multiple-output (SIMO), are employed to strengthen the robustness of the transmitted signal against channel fading. This paper studies the performance of protograph-based low-density parity-check (LDPC) codes with receive antenna diversity. We first propose a modified version of the p...
متن کاملPerformance of Spread OFDM with LDPC Coding in Outdoor Environments
In this paper, the performance of OFDM systems that utilize coding and spreading is presented. The proposed systems operate in outdoor environments and achieve coding gains through the use of Low-Density Parity-Check (LDPC) encoding. It is shown here that by introducing HadamardWalsh spreading in coded OFDM, additional gain in performance can be attained relative to uncoded as well as LDPC code...
متن کاملLDPC Coding for Performance Enhancement of MC-CDMA System
A turbo block code (TBC) technique for improving the performance of a multi-carrier code division multiple access (MC-CDMA) system in terms of bit error rate (BER) is proposed in this paper. The objective of this work is to develop a coding scheme that generates low BER code-words. By implementing a time domain TBC, designed using powerful low density parity check (LDPC) code, the BER performan...
متن کاملEnvironmental and performance analysis of SAW-based RFID systems
This paper describes the environmental effects and performance analysis of 2.45 GHz Surface Acoustic Wave (SAW) based RFID systems. Piezoelectric materials and their underlying principles are reviewed to describe the nature of SAWs. A performance analysis is conducted to measure the readability and read range for individual tags, compared to multiple tags in a field environment. On the other ha...
متن کاملSearch Based Weighted Multi-Bit Flipping Algorithm for High-Performance Low-Complexity Decoding of LDPC Codes
In this paper, two new hybrid algorithms are proposed for decoding Low Density Parity Check (LDPC) codes. Original version of the proposed algorithms named Search Based Weighted Multi Bit Flipping (SWMBF). The main idea of these algorithms is flipping variable multi bits in each iteration, change in which leads to the syndrome vector with least hamming weight. To achieve this, the proposed algo...
