| 摘 要： | 传统的带内同频(IBOC)系统传输容量达到了带宽的极限,在瑞利衰落信道上,由于比特交织编码调制(BICM)能够改善误码率性能且又不受带宽限制,同时基于迭代译码的BICM-ID可以得到更高的编码增益.提出一种基于Turbo BICM-ID的改进信道编码方案可代替传统的IBOC-AM系统,仿真结果表明,当误码率低于10-3时,改进后的信道编码方案可以获得超过1dB的编码增益,所以这种方案的可靠性更高.

| Abstract: | The transmit capacity of IBOC system has reached its limitations for the band- width,Bit interleaved coded modulation（BICM） can improve BER performance without band- width expansion over Rayleigh fading channels . And BICM-ID based on iterative decoding can get a better coding gains. To improve channel coding scheme based on Turbo BICM-ID instead of conventional IBOC AM system. The simulation results show when BER is belowl0^-3 , the im- proved channel coding scheme can achieve more than ldB coding gains. So its reliability is higher. |
