SAMPLE-CORRELATED BIT-LEVEL SYNCHRONIZATION

摘要

A data receiver is activated at periodic intervals to receive data transmitted by any one of a plurality of transmitters having non- overlapping times of transmission. The receiver output is processed to determine the presence of a modulation type and to achieve bit and frame synchronization. One or more messages are received and the data receiver subsequently placed in a dc-activatcd mode for reducing power consumption until the next activation.
