Investigations on product error Control coding techniques

Abstract

In this modern information era, network size and users are increasing day by day. The development of communication systems evolved to digital format from analog format became part of life and caters to various applications like basic voice services, video broadcasting, HD video calling, Home automation, and artificial intelligence. So that data traffic, user density increases exponentially. This needs a data system with more capacity to handle this high volume data communication without error. This makes it a necessity to optimize Error Detection and Correction (EDC) coding as per the present scenario. The error detection and correction code is a method that adds redundant data to empower the robustness of information over the noisy communication channel. This motivates to find a coding scheme to succeed in the high error probability. newlineFirst, the regular LDPC code is designed with the trellis layered algorithm. The reason for considering LDPC codes is the low decoding complexity for a multiuser channel. Usually, the component of a multi-user channel s receiver system is more than a single user channel. This makes it compulsory for a coding system to be less complex. So the trellis structure is added with the layered algorithm by properly designing the parity check matrix. This TLDPC code reduces iteration in the decoding process, also handles well on random errors. Burst Error is a common occurrence in digital communication systems, broadcasting systems, and digital storage devices. To combat this, the product coding systems are designed with TLDPC as one code and BCH, RS, and Turbo code as another code in each process. The advantage of BCH code is its low error output capability newline
