Digital signal processing and direct conversion for multichannel transmitters

Abstract

Abstruct A multichannel transmitter architecture is presented, combining an efficient transmultiplexer algorithm with direct conversion. Direct conversion is chosen for its simplicity and low cost, but it is necessary to compensate for the inherent amplitude and phase imbalances. These imbalances are shown to be frequency dependant in a multichannel… (More)
