Multiple-Symbol-Detection-Based Noncoherent Receivers for Impulse-Radio Ultra-Wideband
نویسنده
چکیده
Multiple-symbol detection (MSD) is a powerful technique to improve the power efficiency of noncoherent receivers. In this paper, we derive the MSD metric for impulse-radio ultrawideband for the general case of biorthogonal pulse-position modulation (bPPM) and relate it to its special cases BPSK and PPM. This unified treatment allows us to conduct a comparison of MSD of amplitudeand pulse-position-based impulse-radio signaling schemes in terms of power and spectral efficiency, as well as in terms of complexity.

متن کاملCoding, Modulation, and Detection for Power-Efficient Low-Complexity Receivers in Impulse-Radio Ultra-Wideband Transmission Systems
Impulse-radio ultra-wideband (IR-UWB) is a promising transmission scheme, especially for short-range low-data-rate communications, as, e.g., in wireless-sensor networks. One of the main reasons for this is its potential to employ noncoherent, hence low-complexity, receivers even in dense multipath propagation scenarios, where channel estimation required for coherent detection would be overly co...
