Coding, 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...
متن کاملLow-Complexity Soft-Output Detection for Impulse-Radio Ultra-Wideband Systems Via Combining Multiple Observations
Avoiding explicit channel estimation, autocorrelation-based receivers enable low-complexity detection of impulseradio ultra-wideband (IR-UWB) signals. In this paper, we present power-efficient IR-UWB detection schemes, which process the receive symbol stream partitioned into overlapping blocks. Properly combining the individual observations gained from each blockwise detection, a final (soft-)d...
متن کاملCapacity of BICM Using (Bi-)Orthogonal Signal Constellations in Impulse-Radio Ultra-Wideband Systems
Bit-interleaved coded modulation (BICM) using (bi-)orthogonal signals is especially well suited for the application in impulse-radio ultra-wideband transmission systems, which typically operate in the power-limited regime and require a very low-complexity transmitter and receiver design. In this paper, we analyze the capacity of BICM using (bi-)orthogonal signals with coherent and noncoherent d...
متن کاملUWB Signal Detection by Cyclic Features
Ultra-wideband (UWB) impulse radio (IR) systems are well known for low transmission power, low probability of detection, and overlaying with narrowband (NB) systems. These merits in fact make UWB signal detection challenging, since several high-power wireless communication systems coexist with UWB signals. In the literature, cyclic features are exploited for signal detection. However, the high ...
متن کاملMultiple-Symbol-Detection-Based Noncoherent Receivers for Impulse-Radio Ultra-Wideband
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-positi...
