Intelligent antennas take advantage of both antenna and propagation technologies. They have the potential to reduce multipath interference, increase signal to noise ratio, and introduce frequency reuse within a confined environment. Several challenges remain however in the growth of intelligent antennas; one of these is the development of new beamforming algorithm for the best use of the received signal. This study focuses on the development and the application of a new simple matrix inversion normalized constant modulus algorithm (SMI-NCMA) for smart antennas. The SMI-NCMA which combines the individual good aspects of Sample Matrix Inversion (SMI) and the Normalized Constant Modulus algorithms (NCMA) is described. Simulation results show that less complexity SMI-NCMA improves the interference suppression and gain enhancement over classical NCMA, converges from the initial iteration and achieves BER (bite error rate) improvements for cochannel interference. |
