The invention discloses a multi-input multi-output power equalization method for a 4T4R symmetrical antenna system. The system includes: a symmetrical four-way transmission and power equalization module and a symmetrical four-way broadband antenna module, and the symmetrical four-way transmission and power equalization module is used to generate, etc. The first radio frequency signal, the second radio frequency signal, the third radio frequency signal and the fourth radio frequency signal with equal frequency and phase are sent to the symmetrical four-way broadband antenna module; the symmetrical four-way broadband antenna module is used to receive the first radio frequency signal, the second radio frequency signal The second radio frequency signal, the third radio frequency signal and the fourth radio frequency signal, and send the first radiation signal, the second radiation signal, the third radiation signal and the fourth radiation signal. The invention forms four radiation signals with consistent amplitude and phase and consistent coverage in space, so that the mobile terminal can receive four radiation signals of equal amplitude and phase when moving within the range covered by the signals, and achieves good indoor coverage effect.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a 4T4R symmetrical antenna system and a multiple-input multiple-output power equalization method. Background technique [0002] With the development of mobile communication technology, multiple-input multiple-output (Multiple-Input Multiple-Out-put, MIMO) technology has been applied in various mobile communication systems to improve system capacity, such as: Long Term Evolution (LTE) system and wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, etc. [0003] Since the proportion of indoor communication services is increasing, it is very necessary to apply MIMO in indoor mobile communication systems. At present, the 4T4R symmetrical antenna system using MIMO and the multiple-input multiple-output power equalization method mainly receive four radio frequency signals of equal amplitude and frequency through symmetrical four-way broa...

AI Technical Summary

Problems solved by technology

However, due to the limitations of the structure, technology and quality of the original indoor coverage system, the coverage, amplitude, and phase of the four radiation signals sent at the same point are inconsistent, resulting in that the mobile terminal can only receive four signals under the signal coverage of the same area during the movement process. Uneven radio frequency signal, poor reception effect, poor MIMO application effect
