Performance Comparison of Channel Coding Techniques for OFDM System

Wireless communication is one of the speedily evolving and dynamic technology areas in realm communication. OFDM an acronym for Orthogonal Frequency Division Multiplexing. It a version FDM which orthogonal subcarriers are closely spaced to maximize bandwidth consumption. By decreasing Inter Symbol Interference (ISI) increasing Signal-to-Noise ratio (SNR), it has enhanced quality long-distance It’s commonly employed digital systems safeguard data from noise interference while also reducing bit mistakes. Convolutional codes, Block two fundamental forms channel codes. codes based on abstract algebra finite field arithmetic. They capable detecting correcting faults. This category includes LDPC Reed Solomon Convolution alternatively created using distinct strong mathematical framework generally utilised real-time error correction. combine all into single codeword. Reed-Solomon block-based used communications, storage, ADSL, among other uses. The BER performance system investigated this paper various coding algorithms.
