Abstract
The performance of a direct-sequence ultra-wide- band (DS-UWB) system coded by super-orthogonal turbo codes (SOTC) over simulated UWB channels is studied in this work. The SOTC scheme is attractive due to its low rate and low- decoding-complexity features. Several receivers are compared for data detection over an indoor IEEE 802.15.3a channel, including the SOTC encoded matched-filter (MF) receiver and the RAKE receiver. The performance of the SOTC-encoded UWB system with different receivers is evaluated by computer simulation. It is shown that the proposed system can achieve significant performance improvement over the DS-UWB system encoded by conventional repetition codes (RC).
