In one embodiment, an optimum configuration is determined based on minimizing Peak-to-Average ratio (PAR) of the channel.
在一个实施例中，基于使信道的峰均比(PAR)最小来决定最佳配置。
While in the meantime, OFDM has its own shortcomings: its sensitivity to a frequency offset and the high peak-to-average ratio.
但是与此同时，OFDM技术自身存在着两个主要的缺点：对频率偏差敏感；
Power meters are often considered for mobile-telephone production testing, because they can quickly measure peak power, average power, and peak-to-average ratio.
