Multicarrier transmission with measures to reduce the ratio of peak to average power

An OFDM (Orthogonal Frequency Division Multiplexing) transmitter converts a serial data stream into parallel data, and segments the parallel data into a plurality of blocks; inserts reference data into each of the segmented blocks; Inverse Fast Fourier Transforms the respective blocks to produce tim...

Summary:An OFDM (Orthogonal Frequency Division Multiplexing) transmitter converts a serial data stream into parallel data, and segments the parallel data into a plurality of blocks; inserts reference data into each of the segmented blocks; Inverse Fast Fourier Transforms the respective blocks to produce time-domain signals; and determines phase factors for the time-domain signals, to reduce a peak-to-average power ratio (PAPR).
