V-band high-speed data transmission near-field communication system

Abstract

The invention discloses a V-band high-speed data transmission near-field communication system, and aims to provide a data transmission system which is high in data transmission rate, low in bit errorrate and high in reliability. According to the technical scheme, an equipment platform end module and a vehicle-mounted end module respectively complete encoding and modulation of data transmission information through respective communication baseband processing modules, complete up-conversion through respective antennas and channel modules, and radiate to space; And finally, the equipment platform end module receives the wireless signal from the vehicle-mounted end module by using the antenna and the channel module of the equipment platform end module; Demodulation and decoding are completedthrough a communication baseband processing module of the down-converter. wherein the vehicle-mounted end module is connected with the equipment platform end module and sends data to the equipment platform information processing and control system, and meanwhile, the vehicle-mounted end module also receives a wireless signal transmitted by the equipment platform end module through an antenna and achannel module of the vehicle-mounted end module to complete bidirectional 50Mbps full-duplex wireless data transmission within a dynamic range with the action distance of 10-30m.

Description

technical field [0001] The invention relates to a short-distance communication (NFC), a high-speed data transmission technology, in particular to a near-field communication system capable of realizing V-band short-distance high-speed data transmission. Background technique [0002] Near Field Communication (NFC), also known as Near Field Communication, is a standards-based short-range wireless connectivity technology that enables simple and secure two-way interaction between multiple electronic devices. Usually, the sending and receiving parties use radio waves to transmit information, and it can be transmitted within a range of tens of meters, which can be called short-distance wireless communication, or short-distance communication technology. The propagation conditions of a wireless communication system are generally divided into two types of environments, line-of-sight (LOS) and non-line-of-sight (NLOS). Under the condition of line-of-sight, the wireless signal propagat...
