Digital Beam Forming Using RLS – QRD Algorithm

Digital beam formers are a means for separating a desired signal from interfering signals. This paper describes the GSC technique using the QRD Algorithm and RLS QRD Algorithm for digital Beamforming. Today the demand of high data rate services is increasing very highly in wireless communication. At the same time the need to support more users per base station is also increasing. The result is that the higher data rates and higher capacities become the pressing need. To increase the capacity the attempts are made to increase the traffic within the fixed bandwidth. But increasing the traffic within the fixed bandwidth creates more interference in the system and the result is degradation of signal quality. The interference can be reduced by using the sectored antenna in place of omnidirectional antenna. Figure-1.
