Abstract
A low-complexity, high performance demodulation algorithm suitable for ultra-wideband Impulse radio (UWB-IR) Is developed. Capitalizing on the recently proposed acquisition scheme based on dirty templates (TDT), the novel demodulator can cope with unknown timing offsets, unknown time-hopping spreading codes, and unknown multipath channels. Both data-aided (DA) and non-data-aided (NDA) TDT schemes are considered. Performance of the resultant TDT-based demodulator Is evaluated and shown to be robust to timing estimation errors. Comparisons are provided with the UWB-RAKE receiver when timing errors are absent. It Is asserted that the TDT-based demodulator outperforms the RAKE with limited number of fingers In the medium to high signal-to-noise-ratio (SNR) range. Analytical results are corroborated by simulations.
