Peak-to-average ration reduction algorithms for multicarrier modulation systems

dc.creatorSingleton, Victor Cody
dc.description.abstractMulticarrier modulation (MCM) systems signals have found increasing use in modern communication systems, including both wireline and wireless environments. However, MCM signals have the potential to contain large instantaneous peaks that increase the resolution requirements of the A/D-D/A converters as well as the dynamic range requirements of the transmitter. By limiting the maximum amplitude of the MCM signal (clipping), it is possible to reduce these requirements on the transmitter's analog front-end circuitry. However, if the transmitter clips the MCM signal, information is lost and the receiver may not be able to properly demodulate the signal. Applying a peak-to-average ratio (PAR) reduction algorithm at the transmitter can mitigate the adverse effects of clipping a MCM signal. The performance and implementation complexity of existing PAR reduction algorithms in addition to a novel PAR reduction algorithm were evaluated via simulation, and these results will be discussed and contrasted. PAR reduction methods that require no additional processing at the receiver were evaluated as well as methods that require receiver intervention.
