Abstract

Subband array processing are considered a promising method in the fields of echo cancellation and sonar. With the growth of wideband communication service, computation load and real time performance of adaptive antenna array become one of the key issues in wideband mobile environment. In the paper we apply subband processing technology to wideband beamforming of mobile communications instead of conventional space-time processing. By using this scheme, The reduction in computation becomes viable with additional advantages such as parallelisation of processing tasks and reduced spectral dynamics.
