摘要
通过在OFDM通信系统中应用新型差分空时分组码(DSTBC),获得编码增益,无需信道估计。相比传统DSTBC彻底解决常见的星座图扩张问题,改善系统误帧率约1dB左右。
By using new DSTBC in OFDM communications system channel estimation is nto necessary and coding gain is gotten. The problem of constellation expansion can be completely resolved and frame error rate （FER） is improved by 1dB around compared with traditional DSTBC.
