Signal receiving and processing method and system in mobile communication

Abstract

The invention discloses a signal receiving and treating method in mobile communication and a system thereof. The signal receiving and treating method in mobile communication comprises the following steps of: receiving a signal; judging whether the received signal contains a valid signal activating region or not according to a preset judging conduction; if so, carrying out signal treatment of a receiving terminal on the signal in the signal activating region; or no-carrying out the signal treatment of the receiving terminal on the received signal. The signal receiving and treating method in mobile communication and the system thereof have the capabilities of improving the signal treating efficiency of the receiving terminal and reducing the waste of treating resources of the receiving terminal and the operation cost of a receiver.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a signal receiving and processing method in mobile communication and a signal receiving and processing system in mobile communication. Background technique [0002] In a mobile communication system, the process of establishing communication between a terminal and a base station can be roughly divided into two steps, that is, initial access is completed first, and then data communication is performed. The current cell coverage application modes are increasingly diversified, including indoor distributed antenna system coverage, outdoor macro base station coverage, and outdoor cell extension coverage. For the above-mentioned various coverage modes, the receiver directly processes all the received signals with the baseband algorithm of the receiving end according to the traditional processing method, and finally completes the signal analysis. However, this proce...

[0005] Thirdly, in the process of mobile communication, in many cases, due to building occlusion and other reasons, after some time slots are transmitted through the channel and reach the receiving end, the information received by the receiving end is incomplete information. In other words, although the receiving end receives to the signal, but due to the severity of the information loss, part of it is no longer necessary to analyze

[0006] Finally, for multi-antenna systems, especially indoor distributed antenna system coverage modes, in many cases, since different antennas share the same baseband pool, but different antennas have a large degree of physical isolation, they each transmit and receive their own target coverage. In this case, for the same time slot, there are often several antennas in which only one antenna receives the signal, and the other antennas only carry low-power interference signals. Therefore, if other antenna pairs receive the signal The interference signal of the receiving end is also processed, which will lead to a waste of processing resources at the receiving end

[0007] From the above analysis, it can be seen that for the receiving end in mobile communication, in many cases, not all receiving periods carry useful signals, and the traditional receiver’s method of uniformly processing the received signals is inefficient, resulting in a shortage of processing resources at the receiving end. waste
