Abstract :
A baseband differential-detection receiver for DPSK, incorporating a planar extended Kalman filter for Doppler frequency offset estimation and compensation, is presented. Simulations show that its performance is close to the ideal case of no frequency offset. It is ideal for digital implementation and finds applications in mobile radio communications
