摘要

比较了慢跳频非相干M-ary FSK三种次优软判决指标的性能。该信道被认为是具有部分频带干扰的AWGN信道。比较选择的编码方案是二进制卷积(7,1/3)编码。归一化能量指标在噪声干扰信道中提供了良好的性能。箝位平均能量指标在部分频带tone干扰中具有良好的性能，从而表明在覆盖系统中具有良好的性能。

Performance simulations of coded slow frequency hopping M-ary FSK with sub-optimal soft decision metrics in partial band interference

The performance of three sub-optimal soft decision metrics with slow frequency hopping non-coherent M-ary FSK is compared. The channel is considered as an AWGN channel with partial band interference. The coding scheme chosen for the comparison is binary convolutional (7,1/3) code. Normalized energy metrics provide good performance in noise interference channels. Clamped average energy metrics give good performance in partial band tone interference thus suggesting good performance in overlay systems.
