Abstract
The utility model relates to a 60GHz photoproduction millimeter wave wireless communication system and belongs to the electronic technical field. The 60GHz photoproduction millimeter wave wireless communication system comprises an antenna, a 60GHz millimeter wave transceiver module, a data processing module, a first Gigabit Ethernet interface and a second Gigabit Ethernet interface. The 60GHz photoproduction millimeter wave wireless communication system enables a receiver to have a relatively wide dynamic range, has high flexibility and solves a problem that the receiver with a high dynamic range is required by a millimeter wave network access terminal and a client terminal because great attenuation caused by blocking of human and objects at a millimeter wave communication channel, moreover, the receiver has properties of simple structure and easy realization.
Description
Technical field
the utility model belongs to electronic technology field, is a kind of communication equipment.
Background technology
photoproduction millimeter wave (ROF) technology has become one of the technology transmitted broadband service that is hopeful most; It makes Optical Access Network that wired and wireless dual service can be provided; Removable millimetre-wave attenuator technology and Fibre Optical Communication Technology are combined, satisfied the continuous demand of high-speed high capacity radio communication bandwidth.Yet in the ROF system, blocking all of people on the transmission path or object will produce very big decay.The Doppler frequency shift of node motion generation can make receiver performance degenerate in addition, therefore requires receiver must have higher dynamic range and guarantees reliable communication.At present, though traditional receiver structure function admirable, automatic gain control (AGC) and frequency tracking loop (FLL) circuit make the higher demand that is unfavorable for following commercialization of the complicated cost of receiver structure.
Summary of the invention
The technical problem that
the utility model will solve provides a kind of 60GHz photoproduction millimeter wave wireless communication system that is used for the low-cost G Bit data rate of photoproduction millimeter wave WLAN.
The scheme of
the utility model technical solution problem is to adopt antenna, 60GHz millimeter wave transceiving module, data processing module, the first Gigabit Ethernet interface and the second Gigabit Ethernet interface to constitute 60GHz photoproduction millimeter wave wireless communication system; Wherein the end SPDT that transmits and receives of 60GHz millimeter wave transceiving module connects antenna; The data/address bus of data processing module is connected with the D/A port with the A/D of 60GHz millimeter wave transceiving module respectively, and the first Gigabit Ethernet interface all is connected with the high-speed i/o interface of data processing module with the second Gigabit Ethernet interface.Native system adopts single carrier difference bi-phase shift keying (DBPSK) modulation and 1-bit A/D receiving demodulation technology.
can make weak signal have the intensity that is transformed into numeric field when the utility model has sufficiently high gain at preamplifier, do not need automatic gain control, also do not need linear amplification, just can make receiver have the dynamic range of broad.In addition; Amplitude and the unbalance in phase etc. of noise factor, inphase quadrature branch road that can also eliminate traditional receiver Analogue mixer, active filter is to the receiver Effect on Performance; Receive processing procedure and be particularly suitable for using the FPGA technology to realize, make the receiver design and realize having very high flexibility.Native system is that 120 ° of transmitting powers are 1mw in the dual-mode antenna angle, and communication distance is a high-speed data communication of having realized 1000Mbit/s under 0.5 to 20m the situation, and dynamic range is greater than 50dB.Efficiently solve photoproduction millimeter wave network insertion end and user side and cause that owing to blocked by people and object very big decay needs the problem of high dynamic range receiver (SG) at the millimetre-wave attenuator channel.Simultaneously, receiver structure is simple and easy to realization, and has higher dynamic range, is more suitable for commercial cheaply demand in future.
