An Efficient Technique to Implement Encoder and Decoder in Communication System for Error Detection and Correction Golay CodeUsing Golay code

Abstract

Channel noise, crosstalk, and other annoyances can occur. Detecting and fixing anomalies in received data is essential to retrieve the sender's data. The Cyclic Redundancy Check (CRC) is used extensively in data transfer. The Golay binary cyclic codes are the most well-known (an alphabet consisting of two letters). The Extended Bose, Ray–Chaudhuri, and Hocquenghem (EBCH) codes and the binary Golay code are important because they are 3-error-correcting codes. The RS/BCH encoder converts input symbols into an n-symbol code word. Demodulate the QAM with a code phrase. The QAM mode is required to translate data symbols into signal waveforms. Raymond fading sends this altered signal. Artificial sounds and other disturbances may cause data loss on this Rayleigh channel. A demodulator separates the data from the carrier signal prior to decoding. It is fed into the receiver's decoder so that the original information may be recovered. The encoder and decoder employ the Golay coding strategy with CRC methodology to improve security while reducing circuit complexity. In order to alter encoders and decoders, the GOLAY binary coding mechanism must be used. The proposed system is designed to save electricity, reduce delay time, and speed up the encoding and decoding processes.
