Provided is a method for performing channel estimation in an Orthogonal Frequency Division Multiplexed (OFDM) signal. The method includes performing the channel estimation based upon use of reserved tone channel carriers. Furthermore a method is provided for decreasing peak to average power ratio (PAPR) for a multicarrier modulation signal including two or more groups of carriers, by first choosing arbitrary non-zero values for the carrier types within the second group; and then optimally determining non-zero values for the carrier types within the second group based upon a predetermined PAPR threshold, wherein carrier types within the first group include at least one of data carriers, continuous pilots, and scattered pilots; and wherein carrier types within the second group includes reserved tones. |
