ABSTRACT:
The present invention is a receiver for receiving a communication signal divided into a plurality of timeslots, wherein the timeslots include a plurality of channels, including a burst detector for detecting when a selected one of the plurality of channels of the communication is received. The burst detector comprises a noise estimation device for determining a scaled noise power estimate of the selected one of the timeslots, a matched filter for detecting signal power of the selected one of the timeslots and a signal power estimation device, responsive for the matched filter, for generating a signal power estimate of the, selected one of the timeslots. A comparator responsive to the scaled noise power estimate the signal power estimate is also included in the burst detector for generating a burst detection signal when the signal power estimate is greater than the scaled noise power estimate, and a data estimation device, responsive to the burst detection signal, for decoding the plurality of channels.
