Patent ID: 8090043

Claim:
A system for compensating for an imbalance between a first signal and a second signal, the system comprising: a first module operative to record, based on the first and second signals, a first frequency domain parameter and a second frequency domain parameter corresponding to each of a first tone, a second tone and a carrier frequency; and a second module operative to compute at least one time domain compensation parameter based on the first and second frequency domain parameters, wherein: the carrier frequency is a receiver carrier frequency; the first and second signals are received from a transmitter operative to transmit the signals using a transmitter carrier frequency; the receiver and transmitter carrier frequencies differ by a carrier frequency offset the first and the second frequency domain parameters correspond to one of the first and the second tones: the first frequency domain parameter corresponds to a first bin in a discrete-valued frequency spectrum; the second frequency domain parameter corresponds to a second bin in the spectrum; the first bin is contiguous with the second bin; the first module is operative to select the second bin based on the location in the spectrum of the first bin and based on the ratio of the offset, in radians, to Pi radians.
