Analysis of filter-based non-coherent detection of UWB FSK with antenna and multipath effects

We study ultra wideband (UWB) communications over dense multipath channels using receivers with low complexity and develop a generic framework for determining the performance of non-coherent frequency shift keying (FSK) data modulation.

Description
Summary:We study ultra wideband (UWB) communications over dense multipath channels using receivers with low complexity and develop a generic framework for determining the performance of non-coherent frequency shift keying (FSK) data modulation. Detection is achieved using a pair of mismatched bandpass filters (i.e., non-coherent detection using templates consisting of a single path). We take into account the effects of both the antenna system and the multipath channel, and find an expression for the bit error rate (BER). We find that the signal-to-noise ratio (SNR) degradation is similar to other low-complexity receivers studied in the literature.
