Patent ID: 6983026

Claim:
An apparatus for processing base band signals to provide low level signals for amplification that will improve performance of a multi-channel transmitter, the apparatus comprising in combination: a first Transform Matrix (TM) coupled to at least one input signals for providing a plurality of output signals each comprising a combination of phase shifted versions of said at least one input signals; a processing unit coupled to said output signals for modifying according to a predetermined algorithm each of said output signals to provide a plurality of modified output signals; a second TM coupled to said modified output signals for decomposing said modified output signals to provide at least one output base band signals, each of said output base band signals corresponding to one of said input signals; and a compensation function arranged and inter-coupled to one of said plurality of modified output signals and said output base band signals to compensate said one of said plurality of modified output signals and said output base band signals so that said output base band signals are suitable for generating the low level signals that will improve the performance of the multi-channel transmitter.
