Abstract :
A digital wideband receiver signal processing technique using two I/Q channel-based receivers with a sampling timing offset is proposed. With I/Q imbalance compensation, the proposed receiver can maintain high instantaneous dynamic range and cover multiple Nyquist zones thus reducing the receiver´s sampling rate requirement. Simulation results are presented to verify validity of the proposed method. The limitations of the proposed method and possible solutions are also discussed.
