%X Bit error rate(BER)characteristics is researched in this paper under the influence caused by the channel codes and channel statistic.Using mathematic tool such as curve fitting etc.,an empirical model on BER is derived on the basis of extensive experiments.The channel model used is AWGN channel.Turbo codes are used as channel codes. Given certain channel statistic and parameter set,the BER in receiver end can be estimated in sender end using this model.Extensive experimental results demonstrate that this model bears high accuracy,whose average error is around 3%,thus can be used in joint source-channel coding and end-to-end rate-distortion optimization.
