Abstract
Disclosed are a power adjustment method and an apparatus based on low delay power detection before digital pre-distortion. The method comprises the following steps: according to pre-configured system carrier information, obtaining effective carrier information containing an effective carrier channel corresponding to each effective carrier; performing sampling on carrier data of each effective carrier channel according to the obtained effective carrier information, and then calculating combination power Pa of effective carriers before digital up conversion or digital peak clipping cancellation according to the sampling; and using the combination power Pa of the effective carriers to perform power adjustment before digital pre-distortion. The present invention moves power calculation ahead of an up conversion module, fully utilizes inherent delay of digital up conversion and a peak clipping module to offset time required for the power calculation, and effectively reduces system delay.
