Patent ID: 8583068

Claim:
A method for use in an adaptive array, said method comprising: a) generating, for each one of N input signals, an associated one or more shifted output signals, N being at least 2, said shifted output signals associated with each one of said N input signals including respective different time delay shifts or respective different phase shifts, each time delay shift being at least zero, each phase shift being at least zero, said N input signals being derived from at least two received radio signals that were transmitted from a common transmit antenna, said transmitted radio signals having been formed by transmitting one first signal and at least one second signal that i) are in a common frequency channel, ii) are other than a quadrature pair, and iii) are other than spread spectrum signals, and b) generating an adder output signal that is a function of the sum of the products of i) each of said shifted output signals with ii) a respective one of a plurality of weights associated with that shifted output signal, said weights being determined in such a way as to reduce interference in a particular type of signal that said adaptive array was designed to process.
