摘要: A method and apparatus are presented for compensating drifts in access terminals occurring during a sleep time. The includes determining whether time exceeds threshold, buffering domain samples containing acquisition pilots paging channel, powering down RF circuitry the terminal after samples, processing to compensate drift, was paged based upon processed samples. digital front end, an FFT engine coupled symbol buffer engine, processor buffer, memory processor, further comprising instructions executing method.
