Abstract

The invention provides a method and system for testing error rate. Through a succinct and convenient test scheme, the data sent by a radio-frequency unit are received by a data acquisition module, and are transmitted to a personal computer; file transfer protocol (FTP) service is started after the personal computer responses to the information fed back by the data acquisition module to download the received data from a data acquisition card; and the downloaded data are processed and the error rate BER (bit error rate) is calculated.

Description

technical field [0001] The invention relates to the technical field of intelligent testing, in particular to a bit error rate testing method and system. Background technique [0002] Radio frequency testing of WCDMA base stations is a key link in R&D and production. The radio frequency test is divided into transmitter test, receiver test and performance test in strict accordance with the 3GPP25.141 standard. Among them, the receiver and performance test indicators mainly include reference sensitivity, dynamic range, blocking, intermodulation, AWGN and receiving performance under multipath channels. The above indicators are all based on testing the bit error rate (BER) as a means. [0003] The base station includes a radio frequency unit (RRU) and a baseband unit (BBU). The base station design has two different architectures. One is that the radio frequency and the baseband are integrated to form a large module, and the other is that the radio frequency and the baseband are ...
