Abstract

The invention provides an uplink / downlink antenna pulling away device, transmitter, receiver and channel measuring method, relating to the channel measuring technology. The downlink antenna pulling away device used for distributed multilink multiple antenna broadband channel measuring system comprises an electro-optic converter used for modulating a radio frequency signal emitted by the transmitting unit of the distributed multilink multiple antenna broadband channel measuring system into an optical signal, an optical fiber which is connected with the electro-optic converter and is used for transmitting the optical signal generated by modulation of the electro-optic converter as well as an antenna pulling away unit which is connected with the optical fiber, comprises an optic-electro converter connected with the optical fiber and is used for receiving the optical signal transmitted by the optical fiber and demodulating the optical signal into the radio frequency signal. By the embodiment of the invention, the measuring on distributed channel can be more flexible and convenient.

Description

technical field [0001] The invention relates to channel measurement technology, in particular to an uplink / downlink remote antenna device, a transmitter, a receiver and a channel measurement method. Background technique [0002] Under the traditional cellular network architecture, single-link multiple-input multiple-output technology has become one of the mainstream standards of the new generation of wireless communication systems. It is difficult for users to achieve the same spectral efficiency and quality of service (QoS) level as users in the center of the cell. Therefore, the transmitting antenna on the base station side must increase the RF output power to effectively ensure the coverage of users in the edge cell, which increases the output energy consumption virtually. Adapt to the needs of future green communication development. In addition, traditional cells must provide good power control, radio resource management, and handover scheduling when users move at high ...
