Performance enhancement of MIMO/UWB based wireless Body area network

Wireless Body area networks (WBAN) can be adapted for patient monitoring applications. The biological sensors are either implanted or placed on the human body. They measure vital information such as ECG, Blood pressure etc. and transmit them wirelessly to a nearby gateway. Transmission of patient´s health information is done using digital communication system. Due to time dispersive nature of communication channel, the transmitted data gets distorted. As there are multiple wireless devices on the human body, multiple access interference occurs. In this paper, we have evaluated the performance of UWB (Ultra Wideband)/MIMO (Multiple input multiple output) (2×2) WBAN system employing Orthogonal complete complementary (OCC) code as the spread code for UWB system. Simulation results have been obtained to validate the improvement in the performance of the system in terms of bit error rate (BER).
