The use of time-frequency distributions is proposed as a nonlinear signal processing technique that is combined with a pattern recognition approach to identify superimposed transmission modes in a reconfigurable wireless terminal based on software-defined radio techniques. In particular, a software-defined radio receiver is described aiming at the identification of two coexistent communication modes:...
In this work1, a novel DS/CDMA receiver using a High Order Statistics (HOS)-based interference cancellator is presented. In particular, the use of the Shen-Nikias algorithm for multilevel signal estimation in interference-dominated communication systems is proposed. The information signal coming out from the matched filter receiver can be regarded as a multilevel signal corrupted by heavy interference...
