【摘要】：随着无线数字通信技术大发展的趋势,短距离无线数传技术凭借其功耗低,面积小,成本低廉以及实现简单的优点,已经在社会生活的方方面面都起到了重要的作用。比如在消费类电子、家庭电器自动化、工业自动控制以及医学应用等许多领域都有着非常广泛的应用。在对短距离无线数传技术领域的研究中,国外起步的非常早,像德州仪器、英特尔等各大芯片设计制造商都已经掌握了成熟的短距离无线数传芯片设计技术,并相继推出了相应的产品。在国内,这方面的研究还不像国外那么成熟,因此,研究具有自主知识产权的短距离无线数传IP基带芯片已经迫在眉睫。BPSK和2FSK作为常用的短距离无线数字通信制式,虽然比较传统,但是凭借其优良的抗噪声性能以及简单的实现原理,依然在无线通信领域占有一席之地。本文根据课题组科研项目,设计一款基于BPSK和2FSK制式的短距离无线数传IP基带芯片,介绍了无线数字通信系统的具体实现过程,并对其中一些关键问题的解决做了详细的说明和分析。本文的重点包括以下几个方面:1)对于BPSK和2FSK无线数字通信原理进行了简要的概述,并探讨了滤波技术和正交混频技术等在无线数字通信系统的设计中比较重要的基础理论。2)介绍了整个通信芯片系统的算法设计思路。在数字变频系统的基础上,BPSK着重讲述了码元定时同步和载波同步这两个对性能影响比较重要的模块,而2FSK则采用一种了较新颖的调制解调方法。3)在Matlab仿真平台下搭建了整个系统的数学模型,并进行定点仿真,通过仿真结果检查算法设计的可行性,并通过对噪声环境的模拟进行了误码率的仿真,证明算法在功能和性能两个方面均能达到要求。4)采用QuartusⅡ和Modelsim的联合仿真环境将算法进行RTL实现,并通过前仿真验证电路设计的正确性。利用FPGA对整个系统进行了原型验证,为后续的芯片后端工作奠定了基础。最后进行芯片的后端工作,完成了逻辑综合和版图设计。本文围绕上述工作,对整个芯片系统从算法设计到电路架构做了全方位的介绍。从总体设计方案到模块设计细节,说明了设计过程中遇到的问题和相应的解决方法。
[Abstract]:With the development of wireless digital communication technology, short-range wireless data transmission technology has the advantages of low power consumption, small area, low cost and simple implementation. Has played an important role in all aspects of social life, such as consumer electronics, home appliances automation, Industrial automatic control and medical applications are widely used in many fields. In the field of short-range wireless data transmission technology, foreign countries started very early, such as Texas Instruments, Intel and other major chip design manufacturers have mastered mature short-range wireless digital chip design technology, and have launched corresponding products one after another. In China, the research in this area is not as mature as abroad, so, The research of short range wireless data transmission IP baseband chip with independent intellectual property rights is imminent. BPSK and 2FSK are commonly used as short range wireless digital communication system, although it is more traditional, However, with its excellent anti-noise performance and simple implementation principle, it still occupies a place in the wireless communication field. According to the research project of our research group, this paper designs a short-range wireless data transmission IP baseband chip based on BPSK and 2FSK. The realization process of wireless digital communication system is introduced. Some key problems are explained and analyzed in detail. The emphasis of this paper includes the following aspects: 1) briefly summarize the principle of BPSK and 2FSK wireless digital communication. The basic theory of filter technology and orthogonal mixing technology in the design of wireless digital communication system is discussed. The algorithm design of the whole communication chip system is introduced. Based on the digital frequency conversion system, BPSK is introduced. In this paper, two important modules, symbol timing synchronization and carrier synchronization, which have an important impact on performance, are described. While 2FSK adopts a novel modulation and demodulation method. 3) the mathematical model of the whole system is built on the Matlab simulation platform, and the fixed-point simulation is carried out, and the feasibility of the algorithm design is checked through the simulation results. The BER simulation of noise environment shows that the algorithm can meet the requirements in both function and performance. (4) the algorithm is implemented by RTL in the joint simulation environment of Quartus 鈪，
