Minimization of fading effect through novel method of beamforming for NGN wireless systems
A. K. M. Baki · 2017
This paper describes a novel multipath fading effect minimization technique through a novel method of Beamforming algorithm. RMS Delay Spread (RDS) of a channel is highly dependent on beamwidth of deployed antenna systems. Deep fade, which is a bottle neck for high speed wireless networks, causes larger RDS and higher bit error rate (BER). A frequency flat fading channel can trasmit data with smaller RDS and higher bit rate. RDS is reduced if the beamwidth of deployed antenna system becomes narrower. Binomial array and Dolph-Chebyshev array are popular methods of array antenna beamforing, though each of these methods has its own technical limitations. The method of Beamforming described in the paper is technically better which uses a novel concept of Fractional-Powered Binomial coefficients. The method performs better than Binomial and Dolph-Chebyshev array. Superiority of the described method is validated through simulations of realistic antennas and technical analysis of RDS.
