关于C6455 VCP2咬尾卷积译码问题



我从贵网下载了csl_c6455\example内的vcp2_hard_decisions,并在此基础上针对需求译码咬尾卷积。我作了如下修改了参数:1/3, 帧长40,poly参数为:G0 = 33, G1 = 71, G2 = 65,约束长度 = 7,带译码数据是硬比特120,对应量化1 -- -42, 0 -- 42,根据vcp2 user guide文档BM,译码模式为convergent mode。但送入译码,发现结果误码。 参看了www.deyisupport.com/.../53367.aspx 不知哪里还需配置?请教贵公司,多谢!
