Embodiment Construction

[0020] figure 1 It is a flowchart of a method for determining spectrum efficiency shown in an exemplary embodiment of the present invention.

[0021] Such as figure 1 As shown, the method for determining spectral efficiency provided in this embodiment includes:

[0022] Step 101, receiving a communication signal, and determining signal information corresponding to the communication signal.

[0023] Wherein, the communication signal may be collected first, and then the collected communication signal may be processed. For example, in order to collect the communication signal and process the collected signal, a software radio may be used for signal collection.

[0024] Specifically, software defined radio refers to an open architecture that connects modularized and standardized hardware units in a bus to form a basic platform, and implements various radio functions through software loading. Based on the software radio to collect communication numbers, the frequency band, air i...

Abstract

The invention provides a method and device for determining spectrum efficiency. The method includes: receiving a communication signal, and determining signal information corresponding to the communication signal; determining the number of resource blocks included in the signal information, and determining spectrum efficiency according to the number of resource blocks. The present invention determines the number of resource blocks included in the signal information by receiving communication signals, and determines the frequency spectrum efficiency according to the number of resource blocks, and can determine the frequency efficiency without the authority of the base station and the operator, thereby accurately measuring the communication system. effectiveness.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and device for determining spectrum efficiency, and belongs to the field of wireless communication. Background technique [0002] Spectrum utilization is defined as the product of user-occupied bandwidth, (geographical) space and time. The calculation method is: U=B*S*T(1) Among them, U is the spectrum utilization rate, B is the spectrum bandwidth, S is the geometric space, T is the time, and the spectrum utilization rate is an important index to measure the effectiveness of the communication system. [0003] For the operator, the basic data for calculating the spectrum utilization ratio can be directly obtained. Therefore, the operator can directly calculate the spectrum utilization ratio based on the known basic data, and determine the effectiveness of the communication system according to the calculation result. However, for other institutions that need to study the spectr...
