A low-complexity bio-medical signal receiver for wireless body area network

In accordance with the tendency towards an aging society, the wireless communication technology has been gradually used in medical monitoring. Such devices are all with characteristics of low power consumption, low cost, and low complexity. Thus, we want to construct a smart bio-sensing system, which is wireless, tiny, and can be provided for more than one person to use simultaneously. The sensing bio-signal will be sent to the smart analyzing system by wireless transmission. Once the abnormal signal is detected, the smart analyzing system will send out a warning signal. The system can save a lot of medical human resources. This paper accomplished the baseband receiver for the wireless bio-medical signal transmission. The receiver can sustain ten users within one meter. The PER is less than 1 % given SNR=7dB. The total power consumption is 304 μW at 5MHz system clock.
