Patent ID: 8798176

Claim:
A method, in a code-division multiple access (CDMA) receiver, of processing a received signal transmitted over a net channel, comprising: centering an N-tap effective grid-based representation of the net channel, based on coarse channel information, wherein the grid-based representation is based on a sub-chip spacing interval; generating pre-filter coefficients based on the centered N-type effective grid-based representation of the net channel, wherein said pre-filter coefficients are designed to compact the centered N-tap effective grid-based representation of the net channel into a K-tap compacted grid-based representation of the net channel, where K<N; pre-filtering the received signal in the frequency domain, using a frequency-domain representation of the pre-filter coefficients; and equalizing the pre-filtered received signal in the time domain, based on the K-tap compacted grid-based representation of the net channel.
