Post FM-Discrimination Multipath Equalization of MSK Signals

This paper provides an early look at the performance of a post FM-discriminator equalizer of MSK signals. The results build on earlier work for FSK signals that showed a computational and performance advantage over pre FM-discriminator equalization. The BER performance is explored for several multipath channels, and the frequency response of the filters after convergence is compared. While these results confirm that the behavior for MSK signals is similar to previous observations for FSK, they also raise many new questions. Full characterization of post FM-discrimination equalization is the subject of on-going investigation
