Abstract
A method for communication includes, in a transmitter, generating a signal for transmission to a receiver over a frequency sub-band assigned within a predefined system bandwidth, using a selected transmitter carrier frequency. The signal is converted into a phase-compensated signal by applying to the signal, using a phase compensator in the transmitter, a phase compensation that compensates for phase discontinuities caused to the signal due to a frequency difference between the transmitter carrier frequency and a center frequency, which is used by the receiver for down-converting the predefined system bandwidth. The phase compensation depends on the frequency difference. The phase-compensated signal is transmitted to the receiver over the frequency sub-band, using a transmitter front-end module.
