This paper proposes a novel concatenated channel codec for WBANs. It has been used in baseband transceiver to achieve low power consumption, high energy efficiency and high coding gain. It consists of variable-length Reed-Solomon (VL-RS) code, Hamming code, CRC code and Proactive Reed-Solomon Bypass (PRSB) circuits. This structure improves system code gain minimum 4dB and maximum 7.8dB at Bit Error Rate (BER) 10(-3). It uses PRSB technique to proactive reduces the power consumption of decoding according to channel quality. It is designed in 0.18um CMOS technology. The lowest power consumption of whole baseband transceiver is 6.1 mu W for TX and 7.2 mu W for RX at 1.0V. Its energy efficiency is 19.6 pJ/bit for TX and 24.5 pJ/bit for RX at 5 Mbps.
