Abstract:
Method for reducing the number of tuners in an adaptive array for reducing interference in the selected channel of the desired signal of a receiver, where signals are present outside the bandpass of said selected channel and where said adaptive array has a plurality of antennas that provide wideband input signals, each one of said wideband input signals is coupled to weights, output of said weights coupled to input of adder, output of said adder coupled to input of bandpass filter, output of said bandpass filter coupled to input of feedback function, said method comprising the following steps:a. weighting said wideband input signals with associated said weights to generate weighted wideband input signals; b. summing each one of said weighted wideband input signals generated in step a. to generate a wideband summed signal; c. filtering said wideband summed signal generated in step b. to generate the adaptive array output signal in the bandpass of said selected channel; d. processing said adaptive array output signal generated in step c. with said feedback function to generate the feedback signal; e. individually correlating each one of said wideband input signals with said feedback signal generated in step d. to generate a separate weight value for each associated one of said weights; and f. adapting said weights to reduce interference in said adaptive array output signal in said selected channel bandpass.
