Patent ID: 7327779

Claim:
A communication device for W-CDMA signal transmission and reception, which is software configurable, comprising: a W-CDMA transmitter comprising at least one of a RAM and registers; a W-CDMA receiver comprising at least one of a RAM and registers; a signal acquisition circuit; and a digital circuit for phase unbalance precompensation in said W-CDMA transmitter, wherein said digital circuit substantially removes the I, Q phase difference that causes the phases to not have a 90 degree separation, wherein the receiver comprises: a pulse shaping filter; an level control block; a demodulator assigned to track multi-path components received from one base station; and a reference demodulator for S/(N+1) measurements, wherein the level control block comprises: a programmable shifter to perform coarse grain dynamic control; a programmable multiplier to perform fine grain dynamic control; an overflow counter operating on a most significant bit and a second most significant bit; and a saturation logic to clip a result from the multiplier.
