This paper investigates the performance of digital implementation of dual antenna phase diversity system utilizing the Constant Modulus Algorithm (CMA) and Maximal Ratio Combiner (MRC) and proposes a two -antenna CMA/MRC hybrid algorithm for mobile FM reception. Simulation proved that CMA has superior performance in frequency selective multipath (long-delay) with medium and strong signal conditions. On the other hand, the MRC optimizes the Signal-to-Noise Ratio (SNR) output in weak signal conditions. The signal conditions are constantly changing in mobile environment, therefore the appropriate algorithm should be chosen dynamically to optimize signal reception.
