Abstract
The performance of a clamped average energy metric with a slow frequency hopping non-coherent M-ary FSK is studied. The channel is considered as an AWGN-channel with narrowband users of another system occupying part of the frequency hopping slots. Hence the frequency hopping system is an overlay system. The coding scheme chosen is the optimal binary convolutional (7,1/3)-code. The clamped average energy metric gives good performance in an overlay system and clearly outperforms hard decision decoding with traditional MFSK-detection.
研究了慢跳频非相干m - mary FSK箝位平均能量度量的性能。该信道被认为是一个awgn信道，其中另一个系统的窄带用户占用了部分跳频时隙。因此，跳频系统是一种覆盖系统。所选择的编码方案是最优的二进制卷积(7,1/3)码。箝位平均能量度量在覆盖系统中具有良好的性能，明显优于传统mfsk检测的硬决策解码。
