ABSTRACT:
Methods and systems for blocker attenuation using multiple receive antennas are disclosed. Aspects of one method may include receiving wideband signals multi-antenna receiver. The receiver may process received signals that may comprise blocking signals received via the multiple antennas. The blocker received by a first antenna may be suppressed, at least in part, by combining processed signals received by a first antenna with processed signals received by a second antenna. The combining may comprise, for example, adding the two processed signals at either the RF or IF frequencies. The processing of the signals whose blocker is to be suppressed may be gain adjustment. The processing of the other signals used to suppress the blocker of the first antenna may be gain and/or phase adjustment. Accordingly, a blocker received by any antenna may be suppressed, at least in part, by using processed signals received by another antenna.
