Cochannel interference, which occurs when two or more signals share the same spectral and temporal channels, is a major problem in frequency- and time-division multiple access systems. In this paper, we focus on the development and evaluation of a joint maximum likelihood algorithm for simultaneously detecting two cochannel continuous phase modulated (CPM) signals. Particular attention will be given to GMSK, a class of CPM employed in the pan-European cellular communications system.
