Performance evaluation of UWB communications with optimum receivers

Abstract

The performance of ultra wideband (UWB) communications are very important for short range wireless communication to consider with matched filter and correlation receivers are evaluated. The rectangular passband, modulated rectangular and modulated Gaussian waveforms, which is satisfied the UWB signal definition and Federal Communications Commission (FCC) indoor and outdoor limit spectral masks, are used as the transmitted UWB signal. The complex form of Friis' transmission formula is considered as the UWB free space channel. Therefore, the distortion effects caused from the channel are included. The BER performance of each waveform is shown and compared. The results are discussed in the conclusion.
