Problems solved by technology

[0007] However, the electric power consumed by the general TX PA accounts for a large proportion of the power consumption of the entire system, especially the greater the transmitted power, the greater the power consumption
However, the simple linear connection design adopted by the existing TDMA system still consumes a considerable amount of power even when the system is not transmitting data

Embodiment Construction

[0070] The present invention is applied to a transmission power amplifier. The transmission power amplifier is used to control the power of a signal to be transmitted. The main feature of the present invention is to generate a nonlinear power control curve in the power variation region to control the power variation of the signal. , so as to reduce power consumption. The power changing region has at least one transmit power value K and can be divided into a ramp-up region, a ramp-down region and an intermediate ramp region. The generation of the power control curve of the present invention mainly generates the original curve and determines the minimum power value H according to the transmission power value K. The original curve is horizontally divided into an original curve left section FL and an original curve right section FR. Then according to the transmission power value K and the lowest power value H, the left segment ratio SL and the right segment ratio SR are determine...

Abstract

The invention discloses a control device for time slot distance incline which switches a first time slot and a second time slot, wherein the first time slot is provided with a first power value, and the second time slot which is adjacent to the first time slot is provided with a second power value. The control device comprises a power control device used for configuration of a distance incline zone or generating an output power curve, wherein the output power curve is a curve with a down concave shape; and a transient period estimator which is connected with the power control device in a coupling way, and used for estimating a transient period of the time slot distance incline when the output power curve can generate switch.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 6, 2005, an application number of 200510081904.2, and an invention title of "Control Method and Device for Transmission Power Amplifier". technical field [0002] The invention relates to a control method and device of a transmission power amplifier, in particular to a control method and device of a transmission power amplifier applied to a wireless communication system. Background technique [0003] The wireless communication system transmits data to a remote place through the atmosphere, and strengthens the power of the signal through a transmission power amplifier (TX Power Amplifier, TX PA) to prevent the signal from being attenuated into unrecognizable noise before reaching the remote destination. Generally speaking, before transmitting a valid signal, the power of the TX PA needs to be increased to the power level to be sent. This process of increasing...
