Description
Technical field
The present invention relates to a kind of communication equipment, particularly relate to the communication equipment of a kind of support multi-protocol transmission based on software definition.
Background technology
For meeting development and the application demand of network, the particularly demand of wireless network, future broadband wireless communication systems needs to support different air protocol, to provide a user with diversified communication mode, access means and ubiquitous access service.Under this trend, require that Next-Generation Wireless Communication Systems is while supporting higher data transmission capabilities, support to different wireless protocols has higher motility, different network designs and scale had higher adaptability, more readily support the cooperative information between platform to process, there is higher cost performance simultaneously.
For using the wireless communication system of specialized hardware platform, it is typically only capable to realize single network framework and the communication of single standard, its motility and poor universality, it is difficult to meet and support different application scene, the wireless communication needs of differing transmission protocols simultaneously.Use Special Purpose Programmable device architectures, defined and configure the software radio system of communication by software, although disclosure satisfy that the requirement supporting various wireless communication agreement flexibly, but it is the longest to the development process cycle of every kind of agreement, between the various implementation of each quasi-protocol, code portability is poor, developer needs to be familiar with the development approach of every kind of embedded system, technical threshold is higher, and program and debugging acid is less, the specific selection of some specific industry can only be become.
Appearance and application along with general processors (GPP) such as multinuclear CPU (MPU) and Graphics Processing Unit (GPU) accelerators, personal computer (PC) increases substantially in computing capability and performance, GPP can compare favourably with traditional dedicated digital signal processor (DSP) to a certain extent so that the wireless communication system (also known as virtual radio) realized based on GPP is possibly realized.Virtual radio acusector solves wireless communication problems from the angle of more software implementation, utilizes general MPU to replace Special Purpose Programmable device to complete various radio function.Therefore, virtual radio has more preferable motility, versatility, opening and autgmentability than tradition software radio based on Special Purpose Programmable device, closer to the preferable software radio that software is unrelated with hardware, thus is easier to promotion and application.
1999, Massachusetts Institute Technology computer science laboratory V.Bose et al. proposed the concept of virtual radio, replaced dedicated devices to complete digital signal processing with the computing capability of general purpose computer.Its thinking is the key factor in realizing for software radio, the method proposing from the angle of more software implementation to solve wireless communication problems, and a series of software modules designed by operation are verified.This " network structure " being made up of system Workstations has the biggest different from " bus structures " that controlled DSP and FPGA by software and constitute system, although the volume of work station, power dissipation ratio are big by DSP and FPGA institute component parts, but its performance is closer to preferable software radio.
2009, Microsoft develops virtual radio system based on PC, and it utilizes common commercial HPC machine and Versatile RF front-end, adds Kernel Driver, achieve IEEE802.11a/b/g PHY and Medium Access Layer Protocol, can communicate with commercial Wi-Fi hardware.
2011, Intel proposes base station architecture based on IA framework, Intel proposes the concept of cooperative wireless access network (C-RAN) simultaneously, proposes cooperative wireless access network based on virtualization pond, base station, utilizes Intel Virtualization Technology, share virtual base station, reducing optical fiber cost, reduce number of devices, equipment leaves reduction electric power concentratedly, the costs such as site is rented, operation maintenance.During without virtualization, all base stations will meet peak value design requirement, it is impossible to utilizes the characteristic of load change, has had a virtualization, then can rational planned network, the design of base station meets average and requires.
The software radio communication system of existing realization based on GPP has a deficiency following aspects:
Support to many host-host protocols is only considered as multimode manner, and the protocol process module between each layer of communication system couples closely, and form and function remodeling to communication system are the strongest；Meanwhile, the coupling between the protocol processes function within each layer of communication system is closely, various the strongest by the process function reusability of different system Protocol Design；Additionally, wireless network and cable network cannot be compatible.
