OPTIMIZING PAPR PERFORMANCE OF PULSE SHAPING FILTERS FOR SINGLE CARRIER WAVEFORMS

摘要

A technology is described for designing a pulse shaping filter for single carrier (SC) waveforms. A pulse shaping filter can be configured to include an odd pulse shaping filter to output data with a first power metric and an even pulse shaping filter to output data with a second power metric. The first power metric and the second power metric can be derived independent of data inputted to the odd pulse shaping filter and the even pulse shaping filter. One or more filter coefficient values can be selected to apply to the odd pulse shaping filter and the even pulse shaping filter. The one or more filter coefficient values can be selected to reduce the first power metric and the second power metric. A reduction in the first power metric and the second power metric can cause the data to have a reduced peak-to-average power ratio (PAPR).
