Abstract
This study studies the Bit-Error-Rate (BER) performance of matched filter and energy detection receivers in Human Body Communication (HBC) channel model. HBC, as defined by the IEEE 802.15 Task Group (TG) 6, is a Body Area Network (BAN) at frequency band 5-50 MHz, where communication is from body surface to body surface. The Bit-Error-Rate (BER) performance is investigated for Energy Detection (ED) and Matched Filter (MF) receivers. BER performance is studied and compared for Binary Pulse-Position Modulation (BPPM) and Binary Phase Shift Keying (BPSK). Moreover, the effect of varies channel parameters on the BER of studied receivers is investigated, including ground plate area at Transmit (Tx) and Receive (Rx) antennas and distance between Tx and receive antennas through air and body. Results show that the BER of both receivers is not affected by varying channel parameters.
Highlights
Body Area Networks (BANs) have received significant attention in both medical and consumer applications
In this study we study the BER performance of energy detection and matched filter receivers in Human Body Communication (HBC) body area network channel model of the IEEE 802.15.6a at frequency band 5-50 MHz
In the Matched Filter (MF) receiver, the received signal is convolved with the channel and the output is extracted at time t = T and it is considered the optimum detector in Additive-White-Gaussian Noise (AWGN)
Summary
Body Area Networks (BANs) have received significant attention in both medical and consumer applications. The channel model for BAN is required to evaluate the performance of different physical layer proposals and important for the development of any communication link (Yazdan-Doost and Pour, 2009). The first is Narrowband Physical (NBPHY), which oc-cupies the 402-405 MHz range and primarily corresponds with communication with any devices that are implanted into the body These devices can be nodes directly under the skin or deep within the body (Yazdan-Doost and Pour, 2009; IEEE, 1980). In this study we study the BER performance of energy detection and matched filter receivers in HBC body area network channel model of the IEEE 802.15.6a at frequency band 5-50 MHz
