Abstract

We present a technique for blind channel estimation for continuous-phase modulated (CPM) signals received using multiple sensors. By modeling an appropriately-sampled CPM signal as a sequence of temporally-correlated symbols having known statistics, we use the method of Lopez-Valcarce and Dasgupta to blindly estimate the resulting single-user multi-channel model. We discuss Cramer-Rao bounds on the variance of such estimates, including a bound developed by Cirpan et al., and we show the bounds can be tightened by incorporating the source statistics. Simulation results demonstrate the good performance of the technique for several CPM signals and for several multipath channels.
