A receiver (100) employs an apparatus (109) and method (500) for determining transmitted modulation symbols contained in a received communication signal (127). Each of a plurality of memory locations (201-208) is loaded (503) with a binary representation (120) of a corresponding portion of the received communication signal (127). At least three of the binary representations (120) are transformed (505) in parallel into signed magnitudes (121) that correspond to the received modulation symbols. The magnitudes (121) are then used (507, 509) in the search and demodulation process (113) to recover the originally transmitted modulation symbols.

[ What is claimed is:] [1.] In a receiver of a communication system a method of transforming signals comprising the steps of:a) during a first portion of a transform process, performing a first vector mapping, the first vector mapping comprising forming a first group of selectable connections between a memory and a digital computation unit; andb) during a second portion of the transform process performing a second vector mapping, the second vector mapping comprising forming a second group of selectable connections between the memory and the digital computation unit, the second vector mapping differing from the first vector mapping.
