Improvement BER for Different Modulation Techniques in a Rayleigh Fading Channel using Transmit Beamforming Method

Abstract

Beam forming handling strategy utilized as a part of sensor arrays for directional signal transmission or reception. This is accomplished by joining components in antenna array cluster such that signs at specific points encounter productive obstruction while others encounter damaging impedance. Beam forming can be utilized at both the transmitting and accepting closures with a specific end goal to accomplish spatial selectivity. In this paper improvement BER for 16-QAM and QPSK modulation techniques in a Rayleigh fading channel using transmit beam forming method. The simulation done in matlab programming and Error probability is analyzed for different taps channels. Based on the error probability investigation.
