توضیحات:The central motive force for technological progress in the mobile radio field has been the digitization of communications to provide digital communication services including digital voice, message, and mobile internet (data) services. In physical layer technologies for cellular systems, digital modulation and multiplexing schemes abandoned the use of constant envelope signals, since spectrum efficiency with nonconstant envelope signals is given a higher priority than power efficiency with the constant envelope signals. In this scenario, linear modulations, code‐division multiplexing, and the latest orthogonal frequency multiplexing are developed.
