Abstract:
1. A method for using one adaptive array and plurality of antenna elements for reducing first multipath interference of first radio signal, second multipath interference of second radio signal and other interference, where said second radio signal has power much less than said first radio signal, each input of said adaptive array is coupled to separate one of said antenna elements, and said adaptive array is configured for said first radio signal, said method comprising the steps of: a. forming separable signal combination of said first radio signal and said second radio signal in same frequency channel to generate transmit antenna input signal; b. transmitting said transmit antenna input signal generated in step a. to generate transmitted radio signal; c. receiving said transmitted radio signal generated in step b. with said antenna elements to generate antenna output signals; d. reducing said first multipath interference, said second multipath interference and said other interference in representation of said antenna output signals generated in step c. with said adaptive array to generate an adaptive array output signal including representation of said first radio signal with reduced said first multipath interference, representation of said second radio signal with reduced said second multipath interference and reduced said other interference; and e. separating said representation of second radio signal from said representation of first radio signal in said adaptive array output signal generated in step d. to generate a separated representation of said second radio signal.
