A performance enhancement of physical layer at Wi-MAX system with RLDPC code

Abstract

<span>In present wireless communication network, the error correction codes plays the major role for efficient data transmission in noisy environments. To get minimum BER and PAPR has been the main aim towards the field in forward error control coding. Majority of the researchers has considered turbo codes at specific SNR over AWGN channel but have complexity issues with the iterative output decoder and causes degradation in the Wi-Max network system. In this paper, the author presents and evaluates WiMAX physical layer performance with using MIMO technologies, where a Robust-LDPC technique of coding and decoding in OFDM based WiMAX system is consider. The decoding method of RLDPC has processed by Belief Propagation at the logarithmic domain in an iterative manner, the proposed methodology shows good decoding outcome for RLDPC codes at Rician and Rayleigh channel. Moreover, the applicability of our proposed model channel codes is defined under IEEE Wi-MAX standard and the results analysis is done under different code-rate and modulation schemes.</span>

Design and Evaluation of the Efficiency of Channel Coding LDPC Codes for 5G Information Technology

“…The analysis of the structural scheme and model of the communication channel with LDPC codes as well as the analysis of the optimal power distribution in the coded communication systems are conducted [24]. The bandwidth and probability of network failures when using coding schemes based on low-density code constructions are estimated [25][26][27].…”

Transmission performance in compressed medical images using turbo code

“…1, July 2022: 318-327 320 starts with the resource data which is grouped in the transport blocks form [47]. In each TTI, a transport block will first be transferred to the channel coding part, which is made up of two CRC and Turbo coder coders [48]. Knowing that the most used CRC calculations are designed in order to always be able to detect errors of certain types, such as those due for example, to interference during transmission.…”
