Turbo码译码算法在多径Nakagami信道中的修正

Modified Decoding Algorithm of Turbo Code on Multipath Nakagami Fading Channels

分析了宽带 DS/CDMA系统在 Nakagami信道中的性能的基础上 ,针对 Nakagami信道对Turbo码译码提出了修正算法——由 Rake接收输出经最大比例合并等处理后的信号、除以信道幅度参数αmi 的平方之和、以高斯分布计算 Turbo码译码的 γ函数、进行 Turbo码译码 .

Analyzes the performance of DS/CDMA systems on multipath Nakagami fading channels and proposes a modified decoding algorithm of turbo code on multipath Nakagami fading channels, i.e.the signal with maximum ratio combiner divides by the all square of amplitudes of the channel, calculate the probability function γ for Turbo code, and then decode the signal as Turbo decoding.
