摘要

通过外部信息传输(EXIT)图分析，在瑞利衰落信道上，提出了一种由简单的4态速率1/2卷积码和适合标记16QAM码的正交空时分组码(oSTBC)组成的低功耗串联空时分组码(STBC)。在E/sub / b/ N/sub / o = 4.4 dB的情况下，该方案可以在每个信道使用2比特的传输速率下实现低于10/sup -4/的误码率(BER)，这似乎是高效的w.r.t.简单性和功耗效率。

A new high power efficient bit-interleaved concatenated STBC

A new power efficient concatenated space-time block-code (STBC) consisting of a simple 4-states rate 1/2 convolutional code and an orthogonal STBC (oSTBC) with suitable labeling of 16QAM symbols over Rayleigh fading channel with two transmit and one receive antenna is proposed by means of extrinsic information transfer (EXIT) chart analysis. This scheme can achieve a bit error ratio (BER) below 10/sup -4/ for E/sub b//N/sub o/ = 4.4 dB at a transmission rate of 2 bits per channel use, which seems to be highly efficient w.r.t. simplicity and power efficiency.
