Temperature compensated crystal oscillator design in Keysight ADS by A. N. Lyashuk, A. V. Kosykh

“…In contrast to the well-known numerical design of a thermally compensated crystal oscillator in SPICE programs with subsequent analysis of the results in a mathematical program, for example, Mathcad, the proposed method allows us to investigate the real shape of oscillations, the spectral purity of the output signal, take into account the nonlinear influence of the circuit and more subtle effects.…”

Service-based network as a platform: research on a new information communication network architecture by Xiaoyun WANG, Xiaodong DUAN, Tao SUN

“…The deployment of 5G enables the network to expand from serving individuals to the industry.The evolution of mobile communication system was analyzed, and a new architecture development direction-service-based network as a platform was proposed.Facing the fundamental challenge of diversified requirements of industrial scenarios, the new architecture employed “platform” to address the generalization and scalability obstacles, and employed “service” to address heterogeneous characteristics of the network.The network service level assurance could also be guaranteed.The definition, overall architecture and mathematical model of “service-based network as a platform” were given.Based on the innovative practice of 5G service-based architecture (SBA) design, the principles of service design were proposed, and then the hierarchical design ideas were given.…”

Application study of Costas arrays in multiuser radar systems by YAO Jian-guo1, HUANG Qing2

“…The construction and performance of frequency hopping codes were discussed but the emphasis was laid on the construction of Costas arrays.The frequency hopping codes called Costas arrays could be designed to have almost ideal auto-ambiguity and good cross-ambiguity.A mathematical model was established for frequency hop coded waveforms and the conditions for orthogonal sub-pulse were given.The auto-and cross-correlation properties of Costas arrays were illuminated,the practical properties of cross-correlation function of permutation matrices were revealed,the algorithms for computing ambiguity function were presented and the simulation results were demonstrated.After a study of the cross-ambiguity properties of Costas arrays the ways were suggested to reduce interference in a multiuser radar system.…”
