BER Improvement in Rayleigh Fading SIMO Channel Using Hybrid Diversity Combining Technique

Abstract

In this paper, Hybrid Diversity Combining Technique for a wireless system using Binary Phase Shift Keying (BPSK) in a Rayleigh Fading Single-Input-Multiple-Output (SIMO) channel is proposed. In Hybrid technique, the hybridization of Selection Combining (SC) and Maximal Ratio Combining (MRC) is done. An algorithm is developed for implementation on wireless system. All the three basic standalone combining techniques Selection Combining (SC), Equal Gain Combining (EGC) and Maximal Ratio Combining (MRC) are also considered and Bit Error Rate (BER) for Hybrid Diversity Combining technique and basic standalone combining techniques are computed and simulated. Antenna diversity (Receive diversity) is used by using multiple antennas at the receiver side and single antenna at transmitter side. The BER performance of Single-Input-Multiple-Output (SIMO) channel using a Hybrid Diversity Technique to that of the standalone combining techniques is minimized.
