摘要
综合Turbo码和乘积码的特点,介绍了宽带移动通信中的一种先进信道编码方式—Turbo乘积码的编码与译码,提出了一种新的基于Turbo乘积码的SISO(Single-Input Single-Output,单入单出)-OFDM(Orthogonal Frequency-Division Multi-plexing,正交频分复用)方案,并对某移动用户的上行链路通过IMT-2000信道后的性能进行了仿真.仿真和分析表明该系统在信噪比大于15dB时,其误码率可达到10-6,为进一步进行MIMO(Multiple-Input Multiple-Output,多入多出)-OFDM系统的研究奠定了基础.
Turbo product codes （TPCs）, which combine the properties of turbo codes and product codes, are an advanced channel coding scheme in broadband mobile communication systems. The encoding and decoding of turbo product codes are introduced. Then a novel SISO-OFDM system based on turbo product codes is proposed. The system performance in IMT-2000 channels for a uplink mobile user is studied. Simulation results show that Bit Error Rate （BER） of 10^-6 is achieved over IMT-2000 channels at Eb/N0〉15dB. Further MIMO（Multiple-Input Multiple-Output）-OFDM systems research will be based on this work.
