Embodiment Construction
[0038] It has been pointed out above that the introduction of dual-polarization smart antennas will lead to changes in wireless environment factors. In order to ensure the authenticity of the simulation results, the inventors analyzed the changes in wireless environment factors caused by the introduction of dual-polarization smart antennas.
[0039] Beamforming gain files from graphical dual-polarization smart antennas (eg figure 2 as shown, figure 2 The picture on the left is the schematic diagram of the beam in the horizontal direction, and the picture on the right is the schematic diagram of the beam in the vertical direction), compared with the beamforming gain file of the traditional single-polarization smart antenna, the level of the four-element dual-polarization smart antenna Broadening the beam width will introduce more interference from the local cell and neighboring cells to the actual system. At the same time, due to the complexity of the wireless environment, th...

The invention discloses a channel blanket prediction simulation system based on a dual-polarized smart antenna, a method and a dual-polarized smart antenna parameter setting apparatus, which solves the problem of the prior art that is difficult to ensure authenticity of simulation results. The system comprises a wave beam simulation unit, a power attenuation execution unit, a test terminal, and a dual-polarized smart antenna parameter setting unit, wherein the wave beam simulation unit is used for generating a signal meeting a preset emission power and transmitting the signal to the power attenuation execution unit; the dual-polarized smart antenna parameter setting unit is used for determining a link loss value according to a polarization diversity gain value and a polarization loss value, and transmitting the link loss value to the power attenuation execution unit; the power attenuation execution unit is used for attenuating the emission power of the signal transmitted by the wave beam simulation unit according to the loss value transmitted by the dual-polarized smart antenna parameter setting unit, generating a power-attenuated signal, and transmitting the signal to the test terminal; and the test terminal is used for determining a received signal code power value of the power-attenuated signal transmitted by the power attenuation execution unit.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a simulation system and method based on a dual-polarization smart antenna and a parameter setting device for a dual-polarization smart antenna. Background technique [0002] Smart antenna is an important technical feature that distinguishes TD-SCDMA system from 2G system and other 3G systems. It makes full use of space division resources, realizes dynamic spatial filtering, and effectively improves system capacity. It is an indispensable item in TD-SCDMA system. key technologies. [0003] Because the traditional single-polarization smart antenna with a large antenna area will cause the public to mistakenly believe that the intensity of electromagnetic radiation is high, and the resistance is high, and the traditional single-polarization smart antenna also has the defects of large windward area, high difficulty in fixing, and difficult selection and installation. ,...
