A RECEIVER, TRANSCEIVER, TRANSCEIVER MODULE FOR A BODY COUPLED COMMUNICATION DEVICE, A BODY COUPLED COMMUNICATION SYSTEM AND A METHOD OF WAKING-UP A BODY COUPLED RECEIVER OF A BODY COUPLED COMMUNICATION DEVICE

摘要

A receiver module (101), transceiver module for body coupled communication devices (100) and a method of waking-up a body coupled receiver of a body coupled communication device (100) are provided. The receiver module (101) of the body coupled communication device (100) comprises couplers (102) for receiving signals via a body transmission channel (160) which follows a body of a user (150). A wake-up receiver (108) and a main receiver (106) of the receiver module (101) are coupled to the couplers (102). The main receiver (106) may operate in a sleep mode and in an operational mode. The wake-up receiver (108) generates a wake-up signal (107) when signals received via the body transmission channel (160) in a predefined spectral range exceed an energy threshold level. The wake-up signal (107) is provided to a circuitry of the body coupled communication device (100) to directly or indirectly configuring the main receiver (106) in the operational mode.
