摘要

软输出维特比算法(SOVA)用于JTC和无线局域网(WLAN)代表的室内无线信道的数据检测。通过仿真实验对SOVA-SOVA置换作为均衡器后加解码器的性能进行了评价。在这些ISI通道中，超过三次迭代的性能并没有得到很大的改善。第三次迭代时，得到的1 ~ 4 dB比特能量与噪声功率之比接近编码AWGN的性能

SOVA-Based Turbo Equalization and Decoding for Indoor Wireless Channels

The soft output Viterbi algorithm (SOVA) is used for data detection in indoor wireless channels representative of the JTC and wireless local area network (WLAN). The performance of SOVA-SOVA permutation as an equalizer followed by a decoder is evaluated by simulation experiment. The performance does not improve much for more than three iterations in these ISI channels. The results obtained for 1 dB to 4 dB bit energy to noise power approach the coded AWGN performance by the end of the third iteration
