Abstract:

Direct sequence ultra wide band (DS-UWB) is a strong candidate for high data rate (HDR) wireless personal area networks (WPAN) IEEE 802.15.3a standard for achieving up to 480 Mbps. This paper presents a new system design methodology based on a multicode approach where the spreading sequences have a duration longer than the channel impulse response (CIR) with the goal of achieving higher data rates up to 1.6 Gbps. Multiple codes are allocated to one user and transmitted synchronously in a TDMA access scheme. All codes are modulated by the same QAM constellation, the best combination of number of codes and QAM order for achieving the largest range of coverage is illustrated for 4 target rates: 10, 110, 480 and 1600 Mbps. The selection methodology is based on a theoretical SNIR derivation at the output of a linear minimum mean square error equalizer using classical WPAN channels as specified by IEEE 802.15.3a. Compared to the DS-UWB proposal for IEEE 802.15.3a, the proposed system grants around 3 times range increase
