1. We designs a communication protocol on this model , implementing many functions between host computer and radio , such as data transmission , radio management and control , status advertisement , etc . this paper uses the interface protocol , designs a radio link layer protocol , and implements the driver for the radio in linux operating system . after testing and measurement , we conclude that this interface protocol can be a model which uses ethernet interface as a transparent data channel
   本文使用了此接口协议,设计了无线链路协议,并且在linux操作系统中以电台驱动程序的方式实现了接口和链路协议,通过对驱动程序运行情况的测试,说明该接口协议对网络层协议而言屏蔽了以太网作为透明通道的事实,此协议接口模型的可以实现和完成既定的功能和目标。
2. The original design program of counting data acquisition system continue to use the train of thought within dos operating system , but the multitask operating system windows are absolutely distinguished form dos . because the way of system data transmittance are program inquiring , at the same time the acquisition and transmittance process cannot be interrupted . this data transmittance mode within windows will be disturbed by other program ' s interruption and lost the requested data . so we have improved the original design of cd400bx ict data acquisition system . we shift the data transmittance mode from program inquiring to hard interruption , and install fifo cache in front of data channel , in order to guarantee the stability , reliability of data acquisiton and transmittance
   由于计数式数据采集系统的原设计方案沿用了以前dos操作系统下的设计思路，而windows操作系统作为多任务操作系统其运行机制和dos有根本的区别。由于系统采用的数据传送方式为程序查询方式，而数据采集和传送的过程都不能被中断。在windows操作系统下这种数据传送方式会因为其他程序的中断造成数据丢失。
3. Hsupa ( high speed uplink packet access ) is the new technique of r6 , first in this thesis , the hsupa physical layer is introduced in detail . then base on the physical layer technique characteristic , according to the 3gpp simulation requirements and system simulation requirements , the hsupa downlink and uplink can be constructed by using matlab . then the data channel and control channel can be simulated , so the channels performance can be realized , provide the results can be provided to the system simulation , these ground the future practical applications
   Hsupa ( highspeeduplinkpacketaccess ) ? ?高速上行分组接入就是r6版本中的新技术,本文首先详细介绍了hsupa物理层的技术特征,然后以其技术特点为依据,按照3gpp的仿真需求和系统级的仿真需求,使用matlab构建hsupa的上下行物理层链路,对其数据信道和控制信道进行仿真验证,从而了解信道的性能,为系统仿真提供仿真数据,为以后的实际应用打下基础,达到预研的目的。
4. A testbench program is edited to simulate the behavior of the fifo . after the software simulation is accomplished , a real hardware circuit is designed to multiplex two data channels ( 1553b data channel and 1394 data channel ) according to ccsds standard . during the experiment and hardware debugging , the output logic of the fpga is checked up
   设计中，用vhdl语言对高速复接器进行行为级建模，为了验证这个模型，首先使用软件进行仿真，通过编写testbench程序模拟fifo的动作特点，对程序输入信号进行仿真，在软件逻辑仿真取得预期结果后，继续设计硬件电路，设计出的实际电路实现了将来自两个不同速率的信源数据( 1394总线数据和1553b总线数据)复接成一路符合ccsds协议的位流业务数据。
5. Common data interfaces used in radio include rs - 232 , etc . as the rapid growth of data speed in data radio , asynchronous serial port does not meet the need of data transmission of high - speed data radio . data radio is gradually using ethernet interface as high - speed data radio ’ s data interface , to function as a high - speed data channel between host computer and data radio . this paper brings forward a universal radio interface protocol model , whose core is taking ethernet as a high speed data channel in network protocol stack
   本文针对电台的以太网接口,经过对各种电台的功能分析,提出了一种通用的在以太网通信中适用的报文接口协议模型,其核心思想是将以太网作为网络协议栈中内部的高速数据传输通道来使用,作为链路层和物理层之间的内部接口,同时提供电台控制和数据传输两大功能模块。
