Abstract: A communication system receives an input signal along a signal processing path and generates a converted output signal via a digital-to-analog converter (DAC). The signal processing path branches into two different branches, a magnitude branch and a sign branch for different components of the baseband signal. A local oscillator (LO) provides a carrier signal to the signal processing path at the DAC and further generates an LO leakage signal comprising a signed LO leakage and an unsigned LO leakage during the up-conversion of signals of the sign branch with a carrier. An unsigned LO suppression component is configured to reduce or eliminate the unsigned LO leakage and a signed LO suppression component is configured to reduce or eliminate the signed LO leakage form a baseband signal of the signal processing path.
