ABSTRACT:
Transmission waveforms are synthesized from orthogonal subcarriers using appropriate combinations of complex sub-carrier codes. This allows conventional single-carrier signaling (such as GSM and CDMA transmission protocols) to be generated and received using a multicarrier platform that is similar to OFDM. Carrier interferometry provides unprecedented bandwidth efficiency and enables substantial improvements in interference rejection, power efficiency, and system versatility.
