Executive Summary

This paper presents a novel UltraWideBand (UWB), Direct Sequence Code Division Multiple Access (DS-CDMA) aided system designed for the IEEE 802.15.3a UWB channel specifications. Substantial performance improvements can be attained by serially concatenated channel encoding combined with a Unity Rate Code (URC). The authors compare the performance of the iterative aided decoding Correlation (Corr) and Minimum Mean Square Error (MMSE) detectors exchanging extrinsic information between the URC's decoder as well as the outer Recursive Systematic Convolutional (RSC) code's decoder.
