Biomedical sensor research is moving towards portable, wearable and implantable designs. Human body communication (HBC) is a promising data transmission method for low-power and high-speed biomedical sensors. Using the conductive human body as transmission medium, HBC trials has significant potential applications for personal healthcare and sports performance. The human body channel investigation identifies an optimum channel bandwidth of 1MHz to 100MHz. To further show better performance and reduce power consumption, the proposed baseband system for human body channel incorporates forward error correction (FEC) coding and FSK modulation technique. The extended Binary Primitive BCH Codes for compensating the elevated BER as FEC are adopted in HBC. The BCH-FSK Baseband (BFB) system for HBC has performed high-efficiency transmission for human body channel communication (HBCC).
