Abstract
Methods and apparatus taught herein provide for symbol alignment between diversity signals in a communication receiver. For example, in one embodiment, a method of symbol aligning diversity signals in a communication receiver comprises generating diversity sample sets for a received signal and hypothesizing two or more relative symbol alignments for the diversity sample sets. The method further includes jointly determining a preferred relative symbol alignment and a preferred synchronization position for the diversity sample sets by evaluating a function that is dependent on relative symbol alignment and synchronization position according to the hypothesized relative symbol alignments and a number of candidate synchronization positions. In one embodiment, a burst-type communication receiver uses Single-Antenna-Interference-Cancellation (SAIC) processing, and over-samples the received signal to obtain the diversity sample sets as sub-channels of the received signal. A diversity processor in the receiver jointly determines the best relative symbol alignment and synchronization position.
