The time-hopping pulse position modulation (TH- PPM) is one of the most popular approaches for IR-UWB multiuser systems, and a lot of research efforts have been devoted on its performance analysis. In several latest literatures, a method of MAI modeling, as well as the numerical computation of the MAI characteristic function, had been carrid out to derive precision analytical bit error performance,...
Non-coherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. However, it is subject to non-trivial performance degradation due to undesired noise enhancement, especially when the system configuration is inappropriate. This paper mainly concerns the pre-filter bandwidth optimization of the non-coherent receiver. The BER performance expression is derived, and an...
Noncoherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. In this paper, a noncoherent receiver structure with an integration optimization scheme of multiple sub-intervals selection is proposed to alleviate the noise effect in detecting UWB-PPM signals. Based on the derivation and modification of the BER performance closed-form expression of the conventional...
Noncoherent receivers are attractive for pulsed UWB systems due to the implementation simplicity. To alleviate the noise effect in detecting UWB PPM signals, this letter proposes a simple yet flexible weighted noncoherent receiver structure, which adopts a square-law integrator multiplied with a window function. The integrator outputs captured within different integration time windows are weighted...
