Abstract :
FSK modems are commonly used for transmission of intermediate data rate signals (1-8 Mbps) in the microwave bands. Link performance can be limited when operating in multipath environments. This paper investigates the performance gains achieved by using equalization and post FM discriminator adaptive filtering for FSK signals to mitigate the effects of multipath. Performance is compared to nonequalized transmissions over a variety of multipath channels.
