摘要：A system and method for reducing peak to average power ratio (PAR) in singleand multi-carrier transmitters while accounting for the effect of the transmit filters
without significantly affecting a requisite transmission Power Spectral Density (PSD) mask.To this end, in a multicarrier communication system, a DSL transmitter is provided thattransmits a multicarrier symbol having a controlled peak-to-average power ratio (PAR)and which is a function of a plurality of information signals. The transmitter has a powerreducer that reduces the PAR of the multicarrier symbol by modifying a selectedinformation signal of a plurality of information signals, the modified signal including aninformation component, a peak reduction component, and a transmission channelresponse component.
