Abstract
An interference-resilient 60 kb/s–10 Mb/s body
channel transceiver using the human body as a signal trans-
mission medium is designed for multimedia and medical data
transaction in body-area network. The body antenna effect which
interferes with signals in the human body channel is examined.
The body-induced interferences degrade the SIR of the signal to
22 dB in the worst case. In order to overcome the body antenna
effect, a 4-channel adaptive frequency hopping scheme using the
30–120 MHz band
