Abstract:
A method for using one adaptive array for improving the performance of two receivers, where said two receivers consist of a first receiver for receiving the first radio signal and a second receiver for receiving the second radio signal, by reducing interference in said first radio signal and said second radio signal simultaneously, where said second radio signal is explicitly separable from said first radio signal and where said second radio signal is simultaneously transmitted from the same transmitter antenna and in same frequency channel as said first radio signal with a power much less than said first radio signal, each input of said adaptive array coupled to one antenna element, where said adaptive array is designed to reduce said interference associated with said first radio signal, said method comprising the steps of:a. receiving said first radio signal and said second radio signal with each said antenna element to generate antenna output signals; b. reducing said interference in representation of said antenna output signals generated in step a. with said adaptive array to generate an adaptive array output signal containing a representation of said first radio signal and representation of said second radio signal with reduced interference; c. separating said representation of said first radio signal from said representation of said second radio signal in said adaptive array output signal generated in step b. to generate a separated first radio signal for said first receiver and a separated second radio signal for said second receiver.
