Embodiment Construction

[0045] In order to improve the signal receiving sensitivity of the user terminal under the Global System for Mobile Communication (GSM) system and improve the call quality, a new signal receiving method is designed, the method is as follows: in the GSM system, the user terminal uses The diversity antenna in the non-GSM system receives the signal and combines the signal with the main set signal.

[0046] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0047] refer to figure 1 As shown, the main set antenna and the diversity antenna are distributed in the user terminal. Under the prior art, when the user terminal works in the GSM system, it can receive signals through the main set antenna, while in the non-GSM system (for example, the LTE system , WCDMA system) work, you can receive signals through the main antenna and diversity antenna.

[0048] refer to figure 1 As shown, in the em...

Abstract

The invention relates to the field of communication and especially relates to a signal processing method and apparatus under a GSM system, for solving the problems of low signal receiving sensitivity of a user terminal under the GSM system and low communication capability and poor conversation quality in a weak signal environment in the prior art. The method is as follows: in the process when the user terminal receives signals under the GSM system, when the user terminal determines that the signal intensity of first signals received through a main set antenna does not exceed a set threshold, a diversity antenna switch is switched off, the user terminal receives second signals on a preset frequency range where the first signals are received through a diversity switch, the user terminal merges the first signals with the second signals, and complete signals are obtained. In such a way, the signal receiving intensity of the user terminal under the GSM system is effectively improved, the communication capability and the conversation quality of the user terminal in the weak signal environment are enhanced, and at the same time, the utilization rate of components is also improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a signal processing method and device under the GSM system. Background technique [0002] With the emergence of Long Term Evolution (LTE), high-speed Internet access brings excellent experience to users. Because the signal receiving part of the user terminal under the LTE system has two parts: the main set receiving part and the diversity receiving part, wherein, the main set receiving part: the signal passes through the main set antenna to the main set antenna switch (Antenna Switch Module, ASM), and then passes through The duplexer finally reaches the radio frequency integrated circuit (Radio Frequency Integrated Circuit, RFIC, that is, the transceiver); the diversity receiving part: the signal passes through the diversity antenna to the diversity antenna switch, then passes through the filter, and finally reaches the transceiver, and both are completed at the same time ...
