The performance of diversity combining for fast frequency hopped NCMFSK in Rayleigh fading
Several diversity combining methods which were developed to improve the jamming performance of fast frequency hopped noncoherent M-ary frequency shift keying have been investigated in Rayleigh fading. Based on performance results, the best methods in both jamming and fading are normalized envelope detection (NED), order-statistics (OS) NED, and OS-hard decision majority vote combining. They provide an increased robustness and should not be seriously affected by intelligent jamming and changing jammer strategies. Linear and square-law combining also perform well, but they are not as robust in a changing interference environment.<>
