Abstract
Human body communication (HBC) will play an
important role in wireless body area networks (WBANs) because
of its low power and low hardware cost. However, the low-
frequency band of HBC transmitting signal could potentially
interfere with the vital signs such as electrocardiography (ECG)
and electromyography (EMG), especially for the frequency below
2 MHz. In this paper, a new mask-shaping technique is pro-
posed for the HBC transmitter to suppress the mask below
2 MHz, where a digital sigma–del
