METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNALS USING MULTIPLE MODULATION AND CODING SCHEMES IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to the wireless communication systems of a kind of modulation using multiple transmission signals and coding techniques and transmitter. Two or more tones, rather than the pilot tone of position of collision, detection include mixing FSK and QAM modulation (FQAM) symbol from tone; When transmission with signal uses the position of two or more pitch detections, adjacent pilot frequencies collision position apply FQAM power-assisteds active tone tone method, include FQAM symbols which quadrature amplitude modulation of FQAM (QAM) method and a kind of keying frequency displacement (FSK) method combine. ;The 2015 of copyright KIPO submissions
