Abstract:
In a communication device coupled to a computing device, a method of receiving a radio frequency (RF) signal using a plurality of antennas, comprising:a) receiving a first RF signal via a first antenna;b) receiving a second RF signal via a second antenna;c) altering the second RF ignal at a weighter based on a first set of complex weights to produce a modified second RF signal;d) combining the first RF signal and the modified second RF signal to produce a received RF signal;e) coupling the received RF signal to a receiver;f) analyzing a spectrum of the received RF signal to establish a relationship between desired and undesired components of the received RF signal;g) storing the relationship between desired and undesired components of the received RF signal and the first set of complex weights;h) generating at least a second set of complex weights;i) feeding back the at least a second set of complex weights to the weighter;j) repeating steps (a) through (g) for the at least a second set of complex weights;k) selecting a set of complex weights from the first set of complex weights and the at least a second set of complex weights based on the stored relationships between desired and undesired components of the received RF signals to produce a selected set of complex weights; andl) applying the selected set of complex weights to RF signals subsequently received by the first and second antennas.
