In this paper, a unified framework, denoted as generalized nonlinear detection (GND), is developed to encompass existing nonlinear detection technologies as well as further optimize the performance of nonlinear detection for noncoherent impulse radio (IR) ultra-wideband (UWB) receivers. Computer simulations show that independent of absence or presence of narrowband interferences (NBIs), the GND-based receivers can achieve much better bit-error rate (BER) performance than the energy detection (ED) based receivers under both AWGN and multIPath channels. Furthermore, as compared to the existing nonlinear detection algorithms, the GND algorithm with a well selected β value always has the best BER performance and the strongest ability to resist NBIs.
