Claim One:
1. A method for reducing noise included in a receive path of a radio system, comprising the following steps: (a) forwarding a transmit signal from a transmit path of the radio to a nonlinear basis function generator, wherein the transmit signal is either in a baseband frequency range or in a low intermediate frequency range; (b) in the nonlinear basis function generator, generating a first nonlinear basis function signal from the forwarded transmit signal using one of a Volterra series and a Legendre polynomial; (c) forwarding the first nonlinear basis function signal to the receive path; canceling at least a portion of noise in a receive path signal using the first nonlinear basis function signal to obtain a reduced-distortion receive path signal; and (d) generating an additional nonlinear basis function signal from the forwarded transmit signal; wherein canceling the noise in the receive path signal comprises using the additional nonlinear basis function signal in combination with the first nonlinear basis function signal to obtain the reduced-distortion receive path signal.
