Claim Text:
1. A method for use with a mobile electronic device comprising a radio transceiver having at least two signal sources, the method comprising: defining test frequencies for the at least two signal sources; generating a matrix by identifying predicted frequencies for combinations in the matrix with the largest amplitudes; generating and transmitting, by the radio transceiver, simultaneous test signals at the defined test frequencies with the radio transceiver; receiving and acquiring, by a receiver in the mobile electronic device, a spectrum of frequencies generated from the test signals; analyzing the spectrum of frequencies generated from the test signals and identifying the frequencies of observed spurs in the spectrum of frequencies generated from the test signals; comparing the frequencies of the observed spurs with the predicted frequencies; accepting the matrix for use with the radio transceiver if the correlation is satisfactory; modifying the predetermined threshold and generating a new matrix if the correlation is not satisfactory; and transmitting, by the radio transceiver, over an operating frequency, wherein the operating frequency is selected using the accepted matrix or new matrix.
