REDUCTION OF PEAK-TO-AVERAGE RATIO IN OFDM SYSTEMS

摘要

An emitter for modulating and emitting an orthogonal frequency division multiplexing signal through a transmission channel (TC), comprising a frequency-to-time converter for converting symbols to be transmitted into time symbols, and means for serializing and amplifying said time symbol so as to emit it as an OFDM signal through said transmission channel, said emitter further comprising:- Means for clipping said time symbols;- Time-to-frequency convertor for converting said time symbols; and- Means for applying a set of subcarriers of the outputs of said time-to-frequency converter as inputs of said frequency-to-time converter
