A Bit Error Rate (BER) model for end to end communication is proposed to reduce the complexity. The BER model is set up based on the coding parameters and the channel characteristics. By using the BER model, the channel BER can be predicted accurately in the encoder when given the coding parameters and the wireless channel characteristics. Experiments results show that the proposed model own high accuracy and robustness. The average predicted error is not more than 0.34%.
