Abstract :
In this paper, we discuss the hardware development of a UWB sensor node for wireless body area networks. A few unique UWB pulse generation techniques have been discussed. The sensor node transmits multiple pulses per bit to increase the average power of the transmitted signal in order to improve the bit-error rate (BER) performance. The multiple-pulse per bit technique is also used as the coding scheme to identify the individual sensor nodes when more than one sensor forms a network. The sensors nodes are able to transmit body signals up to 2 m with a BER lower than 10-5.
