The diversity principle can be employed to combat the fading nature of wireless communication. In the case of receiver diversity the independent fading paths are connected with multiple receive antennas and the resultant signal can be obtained by combining outputs from antennas. This resultant signal is passed through a standard demodulator. The Bit Error Rate (BER) is the most important parameter in communication system design. Always the reducing nature of BER has been desirable which makes the communication more reliable. In this work selection combining (diversity) scheme is used as receive diversity and the performance of 4-Quadrature Amplitude Modulation (4-QAM) and Differential Phase Shift Keying (DPSK) modulation schemes are compared in terms of average BER and multiple number of receiving antennas.
