Abstract


Microelectronics technology, the development of radio technology and digital communication technologies are closely integrated, and gradually form a wireless data transmission technology. It appears to change the traditional wired transmission status quo is to greatly reduce the dependence of the people on the wired network, eliminating the trouble of laying cable lines, is an important direction of development of the wireless communications technology. In this thesis revolves around the theme of wireless data transmission technology, the following aspects of the study, and draw some conclusion: the first chapter on the overview of the development of communication technology, and then analyze the development of the domestic and international wireless data transmission conditions and trends, come to the use of high-performance, ultra-large-scale integrated circuits, wireless digital communication technology and error correction coding technology is a wireless data transmission technology trends The resulting research significance and main contents of this paper. Chapter 2 analyzes the wireless data transmission system works, then given hardware circuit design and implementation of wireless data transmission system, and propose the appropriate hardware anti-jamming design, and thereby achieve a VLSI-based and digital communication wireless data transmission system hardware design. Chapter 3 gives a wireless data transmission system software design, the use of modular and structured programming, easy to implement the control algorithm, as well as the flexibility of the C language programming; and designed according to the actual needs of the system and the experimental results wireless The communication protocol is proposed 0xFF and 0x00 as the head of the data, to solve the CC1000 anti-interference in the transceiver; given according to the division of the functional modules, each subroutine block diagram. Chapter Firstly, according to the theory of antenna design and schematic knowledge to introduce the monopole antenna electrical characteristics of indicators and impedance matching design and draw monopole antenna propagation distance formula; wireless data calculated based on the actual design parameters propagation distance of the transmission system, and experimentally measured by the wireless data transmission system of the actual propagation distance. Chapter V first on the the BSC channel model and GBSC channel model of the theory; then through the experimental method to establish the BSC and GBSC letter channel model, an analysis drawn GBSC channel model with wireless data transmission system letter Road, the actual model is relatively consistent, for the next a chapter of error correction coding provides a theoretical basis. Chapter First Chapter established GBSC channel model analysis derived error correction coding for wireless data transmission system-RS (255,223) cyclic code; verified by experiment RS (255,223) code has better error correction performance, improve the anti-jamming capability. Chapter VII of the research work done in this paper a brief summary and some conclusions; then
