Abstract :
Blind equalization of multi-component polynomial phase signals (mc-PPS) may arise due to multipath propagation in mobile communications. Using the multi-lag high-order ambiguity function, an algorithm is proposed to estimate the parameters of PPS and FIR channel coefficients. Performance analysis is carried out and Cramer-Rao bounds are compared with simulation results
