Performance of error control schemes for wireless ATM
Wan Zhen-mei · Applied science and technology · 2005
In wireless ATM network,a strong protection mechanism for error codes is needed due to the characters of high bit error rates and lots of bursting errors.This paper presented a hybrid error-correcting scheme for WATM:Phonetic signal was protected by BCH code,image and data were protected by hybrid Ⅱ ARQ with BCH code.The error control scheme was simulated and analysed in Gauss white noise channel.The numerical results show that the cell loss rate is remarkably reduced.Simultaneously,the cell error rate is decreased.
