An efficient hardware-based human body communication transceiver architecture for WBAN applications

Abstract

The wireless body area network (WBANs) technology is a promising technology for Continuous Health care monitoring and real-time support at high speed. Human body communication (HBC) is one of the non-Radio frequencies (RF) overcomes the drawbacks of RF-based wireless standards is as per IEEE 802.15.6 physical layer standards. In this Article, an area and power-optimized HBC digital transceiver hardware architecture are designed for WBAN applications. The proposed HBC Digital Transceiver is designed per IEEE 802.15.6 Physical layer (PHY) standards using the Frequency selection digital transmission (FSDT) method. The Walsh coding mechanism with Frequency shift codes (FSC) is used for frequency spreading and despreading generation in HBC Transmitter and receivers. The HBC Digital transceiver is designed and implemented on Artrix-7 FPGA. The design utilizes < 2 % chip area and works at 255.31 MHz operating frequency on Artix-7 FPGA. The HBC transceiver works with a data rate of 9.52 Mbps by consuming 101 mW of power for 100 MHz carrier frequency. In addition, the HBC transceiver obtains the Bit error rate (BER) ratio of 10-4 by transmitting 10188 bits. The proposed HBC transceiver is compared with exiting IEEE 802.15.6 PHY standards and similar Existing HBC architectures with better performance improvements.
