Abstract

í«Distant positioned radio frequencyí» places transceiver of base station near to antenna and far apart from devices of base station. Using medium frequency transmission, the invention implements technique of í«distant positioned radio frequencyí» in order to solve issue of small covering radius of sub zone, and high cost of base station caused by radio wave propagation property in 2GHz frequency range The medium frequency transmission separates transceiver part in analog radio frequency from digital signal process in base band of devices of base station so as to form a public unit in room and multiple remote front end devices in radio frequency, where interface in medium frequency is located between them. Being connected in series or star form through wired or wireless modes, the interface implements services, reference clock, frequency conversion, encoding and path jointing etc, for various control signals. Features are: convenience and cheap.

Description

technical field

[0001] The present invention relates to a design method of wireless base station equipment in the third generation mobile communication system, more precisely, relates to an intermediate frequency transmission method and an intermediate frequency interface capable of realizing remote radio frequency in the base station equipment of the third generation mobile communication system. Background technique

[0002] The typical design scheme of the base station equipment of the existing mobile communication system is to install the receiving antenna and the transmitting antenna outdoors, install the radio frequency transceiver indoors, and connect the radio frequency transceiver, the receiving antenna and the transmitting antenna with a low-loss radio frequency cable. RF transceivers basically use discrete components or low-integration chip designs.

[0003] In recent years, with the demand for wireless base stations of the third-generation mobile communication sys...
