5G NR frequency shift dual-path MIMO power self-balancing system

Abstract

The invention provides a 5G NR frequency shift double-channel MIMO power self-balancing system. The system comprises a 5G single-channel frequency conversion near-end machine and a 5G single-channel frequency conversion far-end machine. The 5G single-path frequency conversion near-end machine comprises a first single-chip microcomputer, a first input detection module, a clock synchronization module, a first frequency mixer and a first multiplexer. The 5G single-path frequency conversion remote terminal comprises a second single-chip microcomputer, an FPGA synchronization module, a second input detection module, a clock chip, a second mixer, a second multiplexer and an output detection module. Due to the fact that the input detection module and the output detection module are additionally arranged, automatic adjustment is carried out according to the insertion loss value of the passive path, remote dual-path MIMO power self-balance of the active path and the passive path is achieved, adjustment is more accurate, and the MIMO effect is more ideal.

Description

technical field [0001] The invention relates to the field of 5G communication equipment, in particular to a 5G NR frequency-shifted dual-channel MIMO power self-balancing system. Background technique [0002] With the large-scale construction of 5G, the high frequency band propagation loss of 5G network is large. The original antenna on the existing network supports up to 2.7G, which cannot meet the needs of 5G networks of 3.5G and above. The original single set of antenna feeders on the existing network cannot meet the MIMO requirements of the 5G network. 5G generally has a high frequency band of 3.5G and above. Due to device limitations, the existing network 2G, 3G, and 4G networks cannot be smoothly upgraded to 5G networks. If the feeder supporting 3.5G and above is used directly, redeployment is required, the cable cost is high, and the transmission loss is large. [0003] The dual-channel multiple-input multiple-output (MIMO) power generally requires the difference wi...

The existing network's original antenna feeder supports up to 2.7G, which cannot meet the 3.5G and above requirements of the 5G network

The original single set of antenna feeder in the current network cannot meet the MIMO requirements of 5G networks. 5G generally has a high-frequency band of 3.5G and above. Due to device limitations, the existing 2G, 3G, and 4G networks cannot be smoothly upgraded to 5G networks.

If the feeder that supports 3.5G and above is directly used, redeployment is required, the cost of the cable is high, and the transmission loss is large
