Abstract
Timing acquisition may be performed without typical correlation computations by determining a power of a received signal at certain points in time and using the determined power to identify gaps in the received signal. By determining gaps in the received signal, frame timing may be estimated, particularly in time-division networks where the location of guard periods within a frame is known. Gap detection may thus be used for timing acquisition.
