Abstract

Nonlinear algorithms for the joint recovery of cochannel narrowband signals are proposed. For finite impulse response channel characteristics, maximum likelihood and maximum a posteriori criteria are employed to derive cochannel demodulators of varying complexities and degrees of performance. The error rate performance of these joint estimation algorithms is examined through computer simulations
