摘要

提出了一种用于卫星载具/个人通信设施的编码调制方案“编码QTFM”。QTFM是一种带带限制基带LPF的4级连续相位调制(CPM)方案。编码后的QTFM以较高的编码效率(/spl sim/0.9)极大地改善了QTFM的误差性能。该系统采用分块编码和最大似然序列估计。一个简单的(10,9)代码将误码率提高到与带限QDPSK (roll-off factor /spl alpha/=1的提高余弦滤波器)几乎相同的值。

A coded quaternary CPM scheme for data exchange over satellite-vehicle/personal communication applications

A coded modulation scheme named "coded QTFM" is proposed for the purpose of satellite-vehicle/personal communication facilities. QTFM is a 4-level continuous phase modulation (CPM) scheme with bandlimiting baseband LPF. Coded QTFM improves the error performance of QTFM tremendously with high coding efficiency (/spl sim/0.9). Block encoding and the maximum likelihood sequence estimation is adopted in the proposed system. A simple (10,9) code improves the bit error rate to almost the same value attained by bandlimited QDPSK with raised cosine filter of roll-off factor /spl alpha/=1.<>
