Abstract

Trellis-coded multiple-phase-shift-keyed (MPSK) modulation is an effective technique for increasing the bandwidth efficiency of an existing channel while maintaining at least a moderate degree of power efficiency through coding. The authors consider the application of this technique to increase markedly the capacity of a 25-kHz military satellite channel. It is shown that with only minor modifications to the QPSK modem to incorporate 8 PSK and 16 PSK modulation and no modification to the rate-1/2 coder used to transmit 16 kb/s over this channel, transmission rates of 32 kb/s and 48 kb/s, can be supported at E/sub b//N/sub 0/ levels only moderately higher than for the lower data rate. In fact, it is demonstrated that 48 Kb/s can be transmitted within exactly the same bandwidth and at the same E/sub b//N/sub 0/ levels as that required to transmit uncoded QPSK at 32 kb/s at bit error rate of 10/sup -5/.<>

用于高效军事卫星应用的栅格编码MPSK调制
栅格编码多相移键控(MPSK)调制是一种有效的技术,可以提高现有信道的带宽效率,同时通过编码保持至少中等程度的功率效率。作者考虑应用该技术显著提高25khz军用卫星信道的容量。结果表明,仅对QPSK调制解调器进行少量修改以合并8 PSK和16 PSK调制,并且不修改用于在该信道上传输16 kb/s的速率-1/2编码器,可以在E/sub / b//N/sub 0/电平上支持32 kb/s和48 kb/s的传输速率,仅比较低的数据速率略高。事实上,48 Kb/s可以在完全相同的带宽和相同的E/sub //N/sub 0/水平上传输,需要以32 Kb/s传输未编码的QPSK,误码率为10/sup -5/。
