Probability Density Functions of Reliability Metrics for 16-QAM-Based BICM Transmission in Rayleigh Channel
— In bit interleaved coded modulation (BICM), the probability density function (PDF) of the reliability metrics (Lvalues) fully defines the BICM transmission and may be used to ...

UWB Based Positioning in Multipath Channels: CRBs for AOA and for Hybrid TOA-AOA Based Methods
— In this paper we consider UWB (ultra wide band) based positioning. We derive the CRBs (Cramer Rao bound) for AOA (angle of arrival) and for hybrid method using both AOA and TOA...
