| With the rapid development of emerging anti-jamming communication technology,digital processing technology and software defined radio communication technology,the tactics is heading for multimode, wide frequency range and multifunction. At thesame time, the development of electronic techniques put forward higher requirementsfor the data transmission rate, real-time and reliability of communication system. Thepaper proceeds from engineering conditions, put forward a innovative mixed system byusing the software defined radio technology, general-purposed hardware platformtechnology, double-correlation technology, and combining the frequency-divisiondouble-work, time-division-overlab, code division multiaddress and MPSK, this systemmay solve the technology difficulties caused by high rate, real-time and reliability ofdata transmission, achieves the wireless synchronous communication between devices,ensures a real-time data transmission.This paper completed the design of system overall plan and engineering designs,meanwhile I has organized and completed the debugging of single machine and systemand other verified experiments, in addition, I has undertaken the design of radio controlprotocol, design and adjustment of main control board control software by myself. Thispaper analyses the requirements of wireless communication system, and on the basis ofthis puts forward and make sure the system overall plan; allocates the functions of radio,makes the hardware designs and software designs of the parts and frame structuredesign, etc; does the system integration-testing and functional tests of complete machine,gives same testing data and corresponding waveforms. The experiment shows: thewireless communication system which designed in this paper satisfies the requirementof high-efficiency and real-time data transmission, it can be widely used for wirelessdata transmission between ground equipments, and it is especially suitable forapplication of ground devices or emergency telecommunication. |
