Method and system for testing radio-frequency performance of receiver in multi-antenna channel environment

Abstract

The invention discloses a method and a system for testing the radio-frequency performance of a receiver in a multi-antenna channel environment. The system comprises a system simulator, a space channel module and equipment to be tested, which are sequentially connected. The system simulator is used for simulating the functions of a base station to generate original signals and measuring and / or calculating conventionally processed signals of the equipment to be tested to determine the radio-frequency performance of a receiver in the equipment to be tested; the space channel module is used for simulating the transmission and reception of the primary signals at an antenna port and sending the output signals to the equipment to be tested; and the equipment to be tested is used for conventionally processing the signals.

Description

technical field [0001] The invention relates to a communication system, in particular to a method and a system for testing the radio frequency performance of a receiver when the communication system includes multiple transmitting antennas and / or multiple receiving antennas. Background technique [0002] With the development of mobile communication, communication speed and coverage have been greatly improved. In order to achieve the maximum communication speed and the widest coverage, many emerging technologies have emerged, such as multiple-input multiple-output antenna technology. Multiple-input multiple-output antenna technology uses multipath to provide higher data throughput without occupying additional radio frequencies; utilizes the spatial multiplexing gain provided by multiple-input multiple-output channels to increase channel capacity; utilizes multiple-input multiple-output The space diversity gain provided by multiple channels improves the reliability of the chan...

Problems solved by technology

[0003] However, all wireless technologies face the challenges of signal fading, multipath, increasing interference and restricted spectrum

The more complex the technology, the more complex the environment of the corresponding radio channel

Moreover, with the increase in the number of antennas used, the complexity of implementing MIMO antenna technology is greatly increased, thereby limiting the number of antennas used, and the advantages of multi-antenna technology cannot be fully utilized.
