Combining CCDF and EVM to assess 802.11 transmitters
Sep 1, 2004
By Christian Olgaard OFDM signals are characterized by fast-varying amplitudes with high peak-to-average power ratios. To minimize power consumption and yield the highest efficiency, the transmitter's RF power amplifier must be operated with some degree of compression....
