Problems solved by technology

Multi-carrier signals are the synthesis of single-carrier signals, the variability of the frequency point and power of each carrier, and the uncertainty of the envelope of multi-carrier composite signals, all of which bring great difficulties to multi-carrier power control.

Embodiment Construction

[0011] A kind of broadband GSM multi-carrier closed-loop power control method of the present invention, the circuit structure involved in it, such as figure 1 As shown, it includes:

[0012] The power control module 116 receives the configured power control data and each carrier frequency information, invokes the corresponding uphill and downhill curve data, obtains the dynamic power control data and the corresponding static power control data, and receives the actually detected processed power Envelope data; RF down-converter 121 receives a part of the signal coupled back from the antenna port to realize down-conversion, and outputs an analog intermediate frequency signal; analog-to-digital converter 120 receives the analog intermediate frequency signal output from the RF down-converter 121 to realize Analog-to-digital conversion: several digital down-converters 117-119 respectively receive the digital intermediate frequency signals output by the analog-to-digital converter 1...

Abstract

The present invention relates to a broadband GSM multicarrier closed-loop powre control equipment, including radio down converter, A / D converter, several digital down converters, several baseband processing units, several digital up converters, several digital multipliers, digital adder, D / A converter, attenuator, broadband sender and power control module. The power control module can be used for receiving configuration power control data and all the carrier frequency informations, and calling correspondent up and down slope cure data, and obtaining dynamic power control data and static power control data, at the same time receiving actually detected and processed power envelop data.

Description

technical field [0001] The invention relates to a wideband GSM multi-carrier closed-loop power control method. Background technique [0002] GSM communication system is currently the most mature digital cellular mobile communication system with the largest market share in the world. It adopts digital wireless communication technology combining FDMA and TDMA. One of the effective measures to improve the system capacity is to increase the spectrum utilization rate, and the specific form is to reduce the interference between channels. Power control is an important means to reduce multiple access interference, which shows the necessity of power control in communication systems. [0003] The principle of power control is: when the maximum transmission power is not required to achieve good transmission quality, the transmission power of the transmitter is adaptively reduced. That is, the average transmission power of the mobile station and the base station is reduced under the p...
