Abstract
The present invention provides a CDMA receiver which uses less expensive, more manufacturable digital filters in combination with noise cancellation circuitry to attenuate highly correlated signals. In addition, the CDMA receiver employs digital IF sampling in the baseband conversion process to remove superimposed DC voltages from the baseband data, obviating the need for DC offset voltage generators.
