Abstract

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
