Abstract

The present invention relates to a synchronous pulse transmission method, device and system. Obtaining a communication radio frequency signal, extracting a first synchronous pulse signal from the communication radio frequency signal; performing amplitude shift keying modulation on the first synchronous pulse signal to obtain a modulated signal; Envelope detection is performed to obtain an envelope pulse, and pulse shaping is performed on the envelope pulse. The ASK modulation mode is used for transmission, so that the delay of the synchronization pulse is low during transmission, and no additional delay circuit is needed, which reduces the complexity of the system; the envelope pulse shaping can restore the synchronization pulse more accurately.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a synchronization pulse transmission method, device and system. Background technique [0002] In a wireless communication system using a time division duplex (TDD) system, uplink and downlink signals are time-divisionally transmitted in the same frequency band. When signals are time-divisionally transmitted at the same frequency, the baseband processor or synchronization controller in the communication system needs to judge the direction of the data to be transmitted according to the content of the special subframe, and switch the uplink and downlink of the transceiver by outputting uplink and downlink synchronization pulse signals. road. In base stations using fourth-generation (4G) and fifth-generation (5G) wireless communication systems, such as small base stations Smallcell or pico base stations Picocell, the access unit (AU) and each remote unit (RU) each cont...
