【摘要】 信道复用技术是多址技术和交换技术的基础,采用信道复用技术可以提高信道利用率,而每一种新的信道复用技术的开发和利用,都开创了通信领域发展的新阶段。目前数字通信系统中常用的复用技术有:频分复用,时分复用和码分复用。本文提出一种新的信道复用技术:素数复用技术,并建立以素数复用原理为基础的通信系统。素数复用的数学基础是素数的特性:唯一分解定理。素数复用利用素数积的唯一分解特性来实现数字信号用户的信道复用,利用数1的乘积不变特性来实现全部用户只传信号1,不传信号0的特性,适合用于终端用户复用或终端功能复用。素数复用通信系统的理论基础是信号的线性分割理论,即把用户的数字信号对应到素数正交坐标系中,再利用特殊的方法实现信号的复合与分解。论文详细论述了素数复用的数学基础、基本原理,素数复用通信系统的工作原理、检错纠错方法、信道容量的估算方法和同步问题的解决方案,并进行了仿真证明。素数复用原理明确,算法简单。其天然的变长度码提高了信道利用率,极高的检错率和高概全错纠正加强了信号传输的可靠性,素数复用积的图样使得自同步法提取帧同步信号十分简便,因此素数复用将会取得重大发展和广泛应用。最后,本文对素数复用在卫星组网、移动通信和家庭网络等领域的应用进行了探讨。更多还原

【Abstract】 The method of channel multiplexing is the base of Channel Reuse and Multiple Access technology, which can be used to improve access channel utilization. The implementation and development of a new method of channel multiplexing will lead to a new stage of development of communication. At present, the methods of channel multiplexing are FDMA CDMA TDMA.This paper presents a new method of channel multiplexing, which is named as Prime-number Division Multiple, and uses its principles on telecommunication system. The method is based on the unique character of prime-numbers product factorization and realizes the channel multiplexing for digital-signal users. According to the product immutability of number 1, all the users can only transfer the logic 1 signals and don’t need transfer the logic 0 signals. It is especially useful for terminals multiplexing or functions multiplexing.This paper discusses the mathematic base and basic principle of Prime-number Division Multiple, and the work principle, the method of error checking and correction, estimating method of channel capacity, solutions of synchronization of Prime-number Division Multiple communication system. then the proof by simulation is given.The principle of Prime-number Division Multiple clear and algorithm is simple. Natural alterable code increases channel utilization. The reliability of signal transmitting is enhanced by extremely high error checking and correction probability. The pattern of Prime-number Division Multiple’s product makes it very convenient to get frame synchronization signal by self-synchronization. Prime-number Division Multiple will develop materially and apply abroad.The paper discusses the application of Prime-number Division Multiple in the field of satellite networks, function multiple of telephone and family network in the end.更多还原
