Design and simulation of a Maximum Likelihood Estimator based Ka-band beacon receiver

Tropospheric effect of Ka-band signals are significant and to study that a beacon receiver is designed and its digital signal processing section is implemented in Simulink. The design is based on Maximum Likelihood Estimator to determine both the amplitude and phase of the signal. The implemented receiver is different from commonly used fast Fourier transform based ones and appears simpler. The implemented receiver is tested with the simulated signal, taken from a RF generator and shown to give desired performance.
