SYSTEM AND METHOD FOR PEFORMING MULTI-ANTENNA TRANSMISSION USING INDOOR WIRELESS SIGNAL COVERING SYSTEM

摘要

A system and method for performing multi-antenna transmission using an indoor wireless signal covering system are disclosed in the invention. The system includes a signal transmission party and a signal reception party that are connected through a radio frequency cable. The method includes that: the signal transmission party determines N paths of signals to be transmitted, performs frequency conversion processing to obtain N paths of signals whose frequency bands do not overlap with each other, and then combines the N paths of signals into one path of signal and transmits it to the signal reception party through the radio frequency cable; the signal reception party divides the received one path of signal into N paths of signals, performs frequency conversion and filtering processing to obtain the N paths of signals before the frequency conversion processing by the signal transmission party, and transmits them to N local antennas correspondingly; and N is a natural number larger than 1.With the invention, the effect that the Multi-Input Multi-Output (MIMO) technology is supported using current operators' indoor distribution system is achieved, the cost to modify the indoor distribution system is saved, and the network service rate and the frequency spectrum usage ratio are improved.
