STTC-OFDM联合传输系统在IEEE802.16信道中的研究
STTC-OFDM is researched in the SUI-3 channel adapted to the IEEE802.16 standard
在空时网格编码(STTC)的基本原理上,将OFDM与之相结合,采用发射与接收分集技术,提出了一种新的STTC-OFDM多天线联合传输系统.并在适合IEEE802.16标准的SUI-3信道模型下,对此系统进行了仿真.仿真结果表明,这种改进的联合传输方案,可有效的对抗无线传播的衰落效应,可以极大的降低系统的误码率(BER),并在不增加系统带宽的前提下,取得较大的分集增益。
Based on the principle of Space Time Trellis Coding(STTC), this paper suppose a new scheme of combine the OFDM and diversity technology, a hybrid TCM-OFDM propagate system is proposed. Then, this system is simulated in the SUI-3 channel adapted to the IEEE802.16 standard .The results show that this system can combat the fading effects efficiently, and the bit error rate (BER) can be great reduce by this improved hybrid scheme, greater diversity gain can be obtained without increase the bandwidth.
