Abstract

There are considered the aspects of application of modulation technique called Cyclic Code Shift Keying (CCSK) and signals processing in different communication applications, such as LPI, satellite navigation, deep space communication, TDCS technique, IoT networks, etc. On a basis of selection of principally new (“complementary”) basis function we state and solve the problem of development of modulation/demodulation technique combining processing simplicity, which is specific for the signals with cyclic structure, noise immunity, specific to orthogonal systems. The estimation of computational cost gain in compare to known orthogonal modulation method and noise immunity gain regarding traditional CCSK allows to define limitary technical parameters where obtained results are advisable to be used. A length of “spectrum spreading” sequences in this case is from N = 64 to N = 1024 covering whole range of practically valuable values. Obtained results allow to essentially extend the term of autonomous operation of low-power devices of the internet of things, increase of energy budget of radiolines in deep space communication systems, make possible the reception of the signals with ultra wide basis in communication systems with increased requirements to energy and structural security.

摘要

考虑了循环码移键控 (CCSK) 调制技术和信号处理在不同通信应用中的应用方面，例如 LPI、卫星导航、深空通信、TDCS 技术、物联网网络等。主要是新的（“互补”）基函数，我们陈述并解决了结合处理简单性的调制/解调技术的开发问题，该技术专门针对具有循环结构的信号、抗噪性、特定于正交系统。与已知的正交调制方法相比，计算成本增益的估计和关于传统 CCSK 的抗噪增益允许定义限制性技术参数，其中建议使用获得的结果。N = 64 到N = 1024 涵盖了整个范围的实际有价值的值。获得的结果可以从本质上延长物联网低功耗设备的自主运行期限，增加深空通信系统中无线电线路的能量预算，使得在通信系统中接收具有超宽基础的信号成为可能。对能源和结构安全的要求。
