Reducing peak-to-average power ratio with multi-parameter set architecture

Methods and techniques are described for reducing PAPR in a system having multiple parameter sets. The PAPR is reduced by means of minimizing a cost function comprising the PAPR for some predefined parameters. For example, PAPR may be minimized for phase and/or amplitude and/or time/cyclic shift adj...

Zusammenfassung:Methods and techniques are described for reducing PAPR in a system having multiple parameter sets. The PAPR is reduced by means of minimizing a cost function comprising the PAPR for some predefined parameters. For example, PAPR may be minimized for phase and/or amplitude and/or time/cyclic shift adjustment to adjust OFDM symbol phase and/or amplitude, or for the number and/or type of parameter sets to be combined for transmission. 描述了用于在具有多个参数集的系统中降低PAPR的方法和技术。PAPR借助于最小化包括用于一些预定义参数的PAPR的成本函数而被降低。例如，PAPR可被最小化以用于相位和/或振幅和/或时间/循环移位调整以调整OFDM符号相位和/或振幅，或用于将被组合用于传输的参数集的数量和/或类型。
