随着海洋资源的深入开发与利用,高精度水下定位技术显得愈发重要。本研究聚焦于水声定位系统中频分多址(FDMA)技术的应用及其效果分析,同时对码分多址(CDMA)技术进行了简要介绍以便进行对比。基于长基线(LBL)定位系统,本研究首先概述了CDMA和FDMA的基本原理以及各自在水声定位系统中的应用场景,特别是CDMA在复杂多目标定位环境中可能面临的挑战。随后,深入探讨了FDMA技术在水声定位系统中的应用优势,并详细描述了基于信号处理、频谱分配和调制解调技术的FDMA系统实现方法。在仿真阶段,通过精心设计的信号处理模块、频谱分配策略和调制解调算法,对FDMA水声定位系统的性能进行了全面的测试与优化。仿真结果表明,在水平圆周运动场景下,FDMA系统的实际定位深度与理论值仅相差0.003 m,相比之下,CDMA系统在同等条件下的误差为0.0556 m。此外,FDMA在降低系统复杂度和成本方面也展现出了显著优势。这些成果验证了FDMA技术在水声定位系统中的有效性,并为进一步提升水下目标的定位精度和系统效率提供了新的思路和方法。

The application-specific multiprocessor system-on-chip(MPSoC) architecture is becoming an attractive solution to deal with increasingly complex embedded applications,which require both high performance and flexible programmability. As an effective method for MPSoC development,we present a gradual refinement flow starting from a high-level simulink model to a synthesizable and executable hardware and software specification. The proposed methodology consists of five different abstract levels:simulink combined algorithm and architecture model(CAAM),virtual architecture(VA),transactional accurate architecture(TA),virtual prototype(VP) and field-programmable gate array(FPGA) emulation. Experimental results of Motion-JPEG and H.264 show that the proposed gradual refinement flow can generate various MPSoC architectures from an original simulink model,allowing processor,communication and tasks design space exploration.

How to use simulink software in grinding system was studied. The method of designing batch grinding sub- system and the steps of building batch grinding blockset were introduced. Based on batch grinding population balance model, batch grinding was simulated with simulink. The results show that the simulation system designed with simulink explain reasonably the impersonal rule of batch grinding. On the basis of batch grinding simulation, the computer simula- tion of mineral processing system with simulink of grinding and classification, comminution, etc, can be properly ex- plored.

In this paper, a complete numerical simulation model of helicopter flight dynamics was established. The modeling of the main aerodynamic components of the helicopter and the aerodynamic interference are taken into account, and the modeling methods of the airfoil aerodynamic model, the induced velocity model and the waving movement model are discussed in detail. Based on the hierarchical and modular modeling principles, the whole simulation model is finally realized on the simulink platform. Finally, the model helicopter data are used to prove the rationality and validity of the modeling theory and method.

Screening is an important process in mineral industry. In this paper, a study has been made to simulate the screening process based on a high-performance MATLAB/simulink software, with an example of simulating the sieving process of a vibrating screen. A simulation model of the sieving process with a vibrating screen （SMSPVS） was proposed, using correlative mathematical models and simulink blocks. The results show that the simulation data was very close to the actual data, The minimum errors of size distribution of oversize and undersize are 0.65% and 0.20%, resoectivelv. The sieving orocess can be accurately simulated by the SMSPVS.
