The spread spectrum (SS) communication is a communication system which has excellent characteristics against noise and is suited to the code-division multiplex. This paper describes a method which reduces the tracking phase error in DLL due to multipath waves in SS communication system. The method is based on the model with a single multipath wave.

The zero structure for non-minimal proper systems in state-space form is investigated. The approach is ‘ geometric ’, and a complete characterization in geometric terms is given of the invariant, decoupling, system and transmission zeros, as defined by Rosenbrock. The first main result is a formula for the transmission zeros. Second, a ‘ canonical ’ lattice diagram is presented of a decomposition of the state space which can be viewed as the ‘ product ’ of the Kalman canonical decomposition and the Morse canonical decomposition. This decomposition gives a straightforward characterization of all zeros just mentioned in terms of spectral properties of subspaces under a certain class of feedback and injection mappings. Via this diagram a number of equivalent formulae for the transmission zeros are derived. The freedom in pole assignment leads to new characterizations for the invariant and system zeros in terms of greatest common divisors of characteristic polynomials. Finally, the relation is demonstrated between certain subspaces and some structural invariants, i.e. the zeros at infinity and the minimal indices of a polynomial basis for the kernel of the transfer function.

The hardwired point to point cabling that has been the mainstay of data handling on naval ships is slowly but surely giving way to more advanced techniques that include data bussing and high speed switching networks. The U.S. Navy's AN/USQ-82(V) Shipboard Data Multiplex System (SDMS) is now installed and operating for technical and operational evaluation purposes on USS Oldendorf , a DD 963 class destroyer. The distributed switching system “SITACS” introduced at ASNE Day 1982 has now been breadboarded. In the foreign arena, NATO standard bus and network interfaces are being implemented in Norwegian, United Kingdom and Canadian shipboard systems. These developments are reviewed, and projections are made regarding future trends in naval data handling systems.

Traditional thinking regarding the data transfer vehicle needed to interconnect elements of a distributed processing combat system generally envisions one or more data busses. This paper presents the somewhat unorthodox viewpoint that a distributed switching network is a better transition vehicle for moving from today's federated architectures to the distributed-processing architectures of the future. The structure and operation of a distributed switching network concept, called Standard Information Transfer Architecture for Combat Systems (SITACS), is briefly described. Simulation results are presented which show throughput and timing values considerably better than that achievable by data bus systems.

The rapidly increasing cost and the uncertain supply of oil provide strong impetus to And ways to conserve ships' fuel and to optimize its use. Underwater mechanical removal of marine fouling from U.S. Navy ship hulls and propellers has been shown to result in immediate and rather substantial fuel savings. The long-term savings from underwater cleaning is not nearly so certain because of the interactions between the cleaning techniques, paint performance, and regrowth of the fouling. Of particular interest is the sensitivity of the fuel savings as a function of cleaning frequency. The following three questions are addressed: Does underwater cleaning lengthen Anti-Fouling (AF) paint service life? Does underwater cleaning really save fuel? Is underwater cleaning cost effective? The answers to these questions obviously depend strongly upon the use of the ships and the manner in which they are operated. For U.S. Navy ships, underwater hull cleaning will save fuel provided adequate attention is given to the scheduling of the cleaning in terms of drydock cycle and deployment. Additional efforts toward optimization of underwater cleaning also are discussed.

Jr. USN:graduated from the U.S. Naval Academy in 1949. He completed his flight training in 1951 and first served in Composite Squadron 33 on board Atlantic and Pacific Fleet aircraft carriers until 1954. He then attended the U.S. Navy Postgraduate School in Aeronautical Engineering and was awarded his Masters degree in SM Aero-Weapons Systems by Massachusetts Institute of Technology in 1957 at which time he was ordered to Heavy Attack Squadron ONE embarked in Atlantic ‘Fleet aircraft carriers. He graduated from the Naval War College Command and Staff Course in 1961 and subsequently sensed on the Staff U.S. Naval Safety Center arid was Operations Officer. Executive Officer and Commanding Officer of Heavy Attack Squadron SIX and Reconnaissance Attack Squadron THREE. From 1968 until 1970 he was Executive Officer of the USS John F. Kennedy (CVA-67) when the ship was commissioned and first deployed followed by duty in the Office of the Chief of Naval Operations (OPNA V) where he served under the Director of Fleet Operations until 1971. Capt. Smith commanded the Fast Combat Support Ship USS Detroit (AOE-4) during her first deployment was Commanding Officer. USS Independence (CV-62): and later returned to OPNAV where he was the Deputy Director of the Aircraft Carrier Programs

The rapid advance of multimedia devices, including sensors, cameras and mobile phones, has given rise to the prevalence of Internet of Multimedia Things (IoMT), generating huge volumes of application-oriented multimedia data. At the same time, network security issues in the multimedia big data environment also increases. Network intrusion detection (NID) system demonstrates its power in preventing cyber-attacks against multimedia platforms. However, the existing NID methods which are based on machine learning or deep learning classifiers may fail when there is a lack of abnormal traffic samples for training in the real-world scenario. We propose a novel approach for intrusion detection based on deep AutoEncoder and Differential comparison named AED, which only requires the normal traffic samples in the training phase. We conduct extensive experiments on two real-world datasets to evaluate the effectiveness of the proposed AED. The experimental results show that AED can outperform the baseline methods of three categories in terms of accuracy, precision, recall and F1-score.
