Abstract

The invention provides a signal power adjustment method and apparatus, and an electronic device. The method comprises the steps of approximately calculating a power adjustment parameter of a to-be-adjusted signal in a logarithm domain according to a logarithm domain power value of the to-be-adjusted signal and a target power value corresponding to the to-be-adjusted signal; the to-be-adjusted signal is adjusted according to the power adjustment parameter to obtain a time domain adjustment signal corresponding to the to-be-adjusted signal, so that the power adjustment parameter of the to-be-adjusted signal is directly and approximately calculated in a logarithm domain, and the problem of high calculation complexity caused by a traditional calculation mode is avoided; therefore, the calculation complexity of signal power adjustment is reduced, and the efficiency of signal power adjustment is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a signal power adjustment method, apparatus, and electronic device. Background technique [0002] At present, the conventional method of signal power modulation in the field of communication is to first convert the power value in the logarithmic domain to the linear domain, and calculate the power adjustment value of the signal in the linear domain. The method usually requires exponential conversion and requires a square root, so that the current conventional signal power modulation method has the problem of high computational complexity. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a signal power adjustment method, apparatus, and electronic device, so as to solve the problem of high computational complexity existing in conventional signal power modulation methods. [0004] In a first aspect, ...
