CHANNEL ESTIMATION AND PEAK TO AVERAGE POWER RATIO REDUCTION IN MULTI-CARRIER MODULATION RECEIVERS

摘要

A method for decreasing peak to average power ratio (PAPR) for a multicarrier modulation signal including two or more groups of carriers, the method comprising: (a) during a first timeframe (i) assigning non-zero values for carrier types within a first of the two or more groups and (ii) assigning zero values for carrier types within a second of the two or more groups after assigning the non-zero values; (b) during a second timeframe (i) choosing arbitrary non-zero values for the carrier types within the second group; and (c) during a third timeframe optimally determining non-zero values for the carrier types within the second group based upon a predetermined PAPR threshold.
