Summary: 
An adaptive rate communication system based on the N-MSK modulation technique is described. Two examples of the system using a 2-MSK adaptive modulation scheme and a 4-MSK adaptive modulation scheme are presented and analysed in slow fading channel. The channel attenuation obeys either Rayleigh or lognormal distribution. The proposed adaptive rate communication system is able to track slow variations of channel attenuation and the average system throughput is therefore increased at a given BER.
