摘要

提出了一种栅格编码调制与空时分组编码相结合的OFDM系统。对错误率(PEP)的分析表明，如果设计得当，可以实现系统的最大分集阶数。与未编码OFDM系统和具有相同状态数的STTC OFDM系统相比，该系统的性能得到了显著提高。

Concatenated space-time block code with trellis coded modulation in OFDM system

An OFDM system of concatenating trellis coded modulation with space-time block coding is proposed. The analysis of pairwise error probability (PEP) shows that if TCM is properly designed the maximum diversity order of the system is achieved. Compared with the uncoded OFDM system and STTC OFDM system with the same number of states, proposed system significantly improves the performance.
