Embodiment 1

[0034] Such as figure 1 As shown, it is a schematic flowchart of a method for signal transmission simulation in Embodiment 1 of the present invention, and the method includes the following steps:

[0035] Step 101: According to the smart antenna beam simulation file, determine the gain and lobe width of each service beam of the smart antenna under standard conditions.

[0036] The beam of a smart antenna refers to the shape formed by the smart antenna transmitting signals in a certain direction. From the type, the beam of a smart antenna can be divided into a broadcast beam and a service beam.

[0037] The broadcast beam is a beam with omnidirectional coverage or sector coverage formed according to specific amplitude and phase excitation, and the smart antenna has one broadcast beam. The service beam is a beam within a certain working angle formed according to specific amplitude and phase excitation, and the smart antenna may have one or more service beams.

Abstract

The present invention discloses a method and a device for simulation of signal transmission, and the main contents thereof are: a traffic beam pattern of a smart antenna used in a simulation process is obtained via analog of a setting algorithm; and when the analog of a setting algorithm obtains the traffic beam pattern of the smart antenna used in the simulation process, the impact of the wireless environment where the mobile terminal located to the gain and the lobe shape of the traffic beam pattern of the smart antenna is fully considered during the simulation; so the traffic beam pattern of the smart antenna used during the simulation can be as truly as possible to reflect the traffic beam pattern of the smart antenna used in the signal transmission process, improving the accuracy of the simulation.

Description

technical field [0001] The technical field involved in the present invention is the field of wireless communication, and in particular relates to a simulation method and device for signal transmission. Background technique [0002] With the development of the third-generation mobile communication system, when simulating the signal transmission of the smart antenna, the simulated GOB (Grid Of Beam, fixed beamforming) algorithm is generally used to obtain the distance between the smart antenna and the mobile terminal used in the simulation. Service beams for signal transmission. The GOB algorithm is a method of fixed beam scanning, which enables the base station to transmit downlink directional signals based on a parameter model (by using the space parameters of the channel). [0003] When the GOB algorithm is used to simulate the signal transmission of the smart antenna, the gain and lobe shape of the service beam used in the simulation process are all fixed values, that is ...
