The BER performance expressions and weighting coefficients of the weighted non-coherent receiver for the UWB-PPM signal were analytically derived.Subsequently

the analytical results were validated via Monte-Carlo simula-tion

and the impacts of the sub-interval width and the timing error were also numerical analyzed.It is illustrated that the weighted receiver is at least 3dB superior to the conventional non-coherent receiver

and is robust to the variations of sub-integration width and the timing error.
