awgn信道下turbo码误比特率模型 在实验基础上，通过曲线拟合等数学工具，得到加性高斯白噪声信道条件下，信道编码采用turbo码，通信系统端到端的误比特率经验模型。

Simulations over awgn and Rayleigh channels, at various signal-to-noise ratios, verify the excellent performance of this novel APEL-turbo scheme. Performance comparisons were carried out between turbo coded APEL, JPEG, and BMP image files. To provi

turbo codes for a certain bits sent as a messages through awgn channel and then through error correcting turbo codes actual data is decoded
