| 摘 要： | 为了提高MIMO-OFDM系统中的空时频分组编码(STFBC)性能,本文提出了一种串行级联空时频分组编码(SCSTFBC)方法,该方法把卷积码作为外码、空时频分组码作为内码,通过交织器,连接内码和外码。仿真结果表明,本文建议的方法随着发收天线数的增加,其性能不断得到改善,在误比特率(BER)为10-3时,本文建议方法与空时频分组编码(STFBC)、空时频网格编码(STFTC)相比,其性能增益分别提高了6dB和8dB。

| Abstract: | In order to improve the performance of space-time-frequency block code(STFBC) for MIMO-OFDM system,a serially concatenated space-time-frequency block code(SCSTFBC) scheme is proposed in this paper.The proposed SCSTFBC choose convolutional code as its outer code and STFBC as its inner code.The two codes are connected to interweaver.Simulation results show that the performance of the proposed scheme is improved increasingly with the number of antennas,the performance gain of the proposed scheme increase 6dB and 8dB respectively than STFBC and STFTC scheme when the bit error rate is 10-3. |
