摘要
提出一种由Turbo与纠正多个随机错误的循环码构成的新型级联码,旨在用纠正多个随机错误的循环码纠正Turbo不能纠正的错误,进一步降低误码率.仿真结果表明:信噪比超过一定值后,此级联码的误码率明显低于传统的Turbo码.
This paper brings forward a new turbo code, which consists of turbo code and cyclic code. Cyclic code corrects the bit error that turbo code can＇ t find. As a result lower bit error rate is attained. The result shows that when signal-noise ratio exceeds certain value, the BER of cascaded code is obviously lower than traditional turbo code.
