Remote equipment, adaptive equalization device and realization methods based on GSM (Global System for Mobile Communications) system

Abstract

The invention discloses remote equipment, an adaptive equalization device of the remote equipment and realization methods of the remote equipment and the adaptive equalization device, which are all based on a GSM (Global System for Mobile Communications) system. On the basis of the traditional remote equipment, the remote equipment also comprises a coupler, a feedback radio frequency circuit, a compensation unit, an analog-to-digital conversion unit and an adaptive equalization computing unit, wherein the input end of the compensation unit is used for receiving various carrier signals, the output end of the compensation unit is connected with the input end of the coupler after sequentially passing through a digital up-conversion unit, the analog-to-digital conversion unit, a downstream radio frequency circuit and a power amplifier, one output end of the coupler is connected with an antenna, and the other output end of the coupler is connected with the control end of the compensation unit after sequentially passing through the feedback radio frequency circuit, the analog-to-digital conversion unit and the adaptive equalization unit. The invention ensures that the carrier signals ofall frequencies emitted by the remote equipment have same coverage area, thereby guaranteeing the normal operation of a GSM coverage network.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a remote device based on the GSM standard, a method for realizing the remote device based on the GSM standard, an adaptive equalization device based on the remote device based on the GSM standard, and the realization of the self-adaptive equalization device method. Background technique [0002] With the continuous development of GSM communication technology, the large-scale construction of GSM network is becoming more and more mature.

Problems solved by technology

However, due to the unbalanced output signal in the effective frequency band caused by the radio frequency circuit and the power amplifier, the GSM carrier signal with the same power and different frequencies output by the digital circuit will output signals with different power and different frequencies after passing through the radio frequency circuit and the power amplifier. As a result, the coverage of GSM carrier signals with the same power at different frequencies is different, which directly affects the application of GSM remote equipment
