This invention discloses a method for reducing power loss of adaptive power feedback by a mobile communication terminal relating to chip adopting digital signals, in which, a supply management circuit provides a relative stable supply to all circuits of a mobile terminal device at its output end to measure the change at this position, and signals entering into RF power amplification can measure envelopes of power of RF power amplification and carry out data sample at the input of the RF amplification and set a final sample point at the output end of the RF amplification after controlling power loss of the mobile terminal circuit based on the test result to the two points to realize test and analysis to the related parameters of mobile terminals and simplify control of output by continuously optimized executing forms.

Description

technical field [0001] The invention relates to a method for reducing power consumption of a mobile communication terminal by an adaptive power feedback device, and belongs to the technical field of mobile communication. Background technique [0002] The normal working time provided by the battery of a mobile communication terminal is one of the most critical factors in the use of mobile communication devices such as mobile phones, because it ultimately determines the mobility and durability of these devices. With the shrinking form factor and increasing functions, battery power becomes insufficient, reducing the practicality of mobile communication products. [0003] Because in a mobile communication terminal, it is necessary to drive the antenna with enough power to transmit the signal to the remote receiver, the RF power amplifier consumes most of the energy. Therefore, the RF power amplifier part of these systems determines the operating time of the system. [0004] St...

Problems solved by technology

However, the current solutions basically use two forms of envelope feedback and power feedback. These feedback controls are in an ideal state and can basically meet the expected control requirements. However, as the application environment changes, it is impossible to fully fit the control curve and achieve the expected target, even increasing power consumption

At present, digital signal processors are also used to make up for the application limitations of the above two methods, but at the same time, this system also brings the complexity of the feedback circuit and the decline in efficiency in certain cases.
