ABSTRACT:
A time division multiple access (TDMA) burst receiver and a method for recognizing and providing a time-of-arrival of a TDMA burst transmission having a selected preamble. The TDMA burst receiver includes a blanker for blanking the TDMA burst transmission when the signal level exceeds a pre-selected noise threshold, a signal threshold detector for providing a first tentative time-of-arrival when a correlation of the TDMA burst transmission and the selected preamble exceeds a first threshold and a second tentative time-of-arrival only when the correlation exceeds a second threshold within a selected time period following the first tentative time-of-arrival, and a state machine for providing an operational time-of-arrival corresponding to the first tentative time-of-arrival when the second tentative time-of-arrival is not received and the second tentative time-of-arrival when the second time-of-arrival is received. A demodulator synchronizes to the operational time-of-arrival for demodulating the TDMA burst transmission and providing an output data sequence. A sequence threshold detector issues a semaphore to the state machine to confirm the operation time-of-arrival when a sequence match between the output data sequence and a sequence of said selected preamble exceeds a sequence match threshold.
