Abstract
A method and apparatus of joint processing a plurality of digital signal streams is disclosed. The method includes transforming a plurality of the digital signal streams from an original domain to a lower complexity processing domain. The transformed plurality of digital signal streams are joint processed, wherein the joint processing includes multiplying samples of the plurality of transformed digital signal streams by a processing matrix. The joint processed signal streams are inverse transformed back to the original domain. Diagonal elements of the processing matrix are adaptively selected to cancel transmission echo signals of the plurality digital signal streams introduced during transmission of the plurality digital signal streams depending upon signal coupling of the plurality of digital signal streams.
