Co-channel demodulation for continuous-phase modulated signals
P.A. Murphy, Gary E. Ford · 2002
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. 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 is given to GMSK, a class of CPM employed in the pan-European cellular communications system.
