Inhalt:
A complete Matlab model is made for a millimeter wave wireless communication system including a four-phase Costas loop for carrier recovery and QPSK demodulation. Simulation results are presented to demonstrate the dynamic behaviour of the Costas loop and the effects of noise, linearity and bandwidth limitations. The time domain results are compared to the frequency domain transfer function derived from the Costas loop parameters.
