| Details | This paper discusses a multipath compensation technique for body area network systems using a pulse-based ultra-wideband method. In the paper, a combined RAKE reception and multi-band template pulse is proposed. RAKE reception is an effective time domain multipath compensation technique. The multi-band template pulses can be used to control the powers of the sub-band pulses and adaptively approximate the received signals. The normalized root mean square error between the ideal received signal and the template pulse is then evaluated. The performance improves when using an iterative weight determination scheme for selective RAKE reception and the multi-band pulses, because the template pulse correlation in each RAKE branch can be reduced and the frequency-selective fading can be compensated. The bit error rate (BER) performance is also evaluated. The results show that the BER is improved and that the number of RAKE branches can be reduced when using the proposed scheme. |
