As the wireless communications process exists interference, This requires that the source side of the channel coding sessions introduce error control coding technology make channel interference transmission losses to the minimum. Through channel coding in this area, the data flow accordingly, The system is a correction and anti-jamming ability, can greatly code to avoid spread of the delivery error occurred. RS code is a kind of very strong correction over M-ary BCH, precisely because of its super-correction capability, After they raised a widespread concern that the current information has become the darling of the era. as a popular technology has been used in digital television and other advanced fields, a bright prospect.
The issue is to be done when using RS codes as channel coding. AWGN channel in the course of transmission error performance analysis, Matlab Simulink built-in visual simulation model of the communication system of coding, modulation, demodulation, decoding and channel frame simulated structures, and then not out simulation applications and application of RS code, different error-correcting capacities and different code length RS code channel coding for the signal-to-noise ratio -- BER curves, Finally compared and analyzed.
