Performance of Energy Detection and Matched Filter Receivers in Human Body Communication Channel

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.
