The analysis of BER in UWB communication system based on group counterchange BCH code
Zhenyu Hu · Sciencepaper Online · 2008
A new coding and decoding method of Bose-Chaudhuri-Hocquenghem (BCH) is proposed which can speed up the computation of coding and decoding as t error correction t (t≥2) code to obtain high capacity and resist the fatal transmission error when communications are carried on Additive White Gaussian Noise (AWGN) channel. The comparison of BER of BCH code and code-repetition codes are given for transmitting PPM-TH-UWB signal and PAM-DS-UWB signal on different signal to noise ratio, and the simulation results are given. It can be concluded that the BCH code has better error correcting ability.
