Abstract:
1. A method of identifying crosstalk in a received signal, the method comprising: collecting received data corresponding to the received signal from a receiver; collecting primary data from a primary transmitter; collecting crosstalk data from a crosstalk transmitter; identifying a crosstalk function corresponding to the crosstalk data; collecting a plurality of sets of crosstalk data from a plurality of crosstalk transmitters, the plurality of sets of crosstalk data comprising a set of strong crosstalk signal data corresponding to a strong crosstalk signal and a set of weak crosstalk signal data corresponding to a weak crosstalk signal; determining whether a timing offset exists between the received data and the set of strong crosstalk signal data; generating a first estimate of any determined timing offset between the received data and the set of strong crosstalk signal data; identifying a strong crosstalk function corresponding to the strong crosstalk signal data; subtracting the strong crosstalk function from the received signal to generate a modified received signal; determining whether a timing offset exists between the received data and the set of weak crosstalk signal data; generating a first estimate of any determined timing offset between the modified received signal and the weak crosstalk signal data; and identifying a weak crosstalk function corresponding to the weak crosstalk signal data.
