Many military communication systems require data rates in the gigahertz range. Usually gallium arsenide technology is chosen for these high-speed applications. However, for device counts in excess of 1000 transistors, the defect level is prohibitively high in gallium arsenide circuits. For these applications, High-speed bipolar silicon technology is an excellent if not the only choice available. This paper presents a design and process for a silicon LSI circuit that is capable of data rates in excess of 1.8 Gigahertz and a divide by 2 circuit that operates at 3.9 Gigahertz. The LSI chip consists of a common building block, used in military communication systems, replicated 16 times, to demonstrate both yield and speed. The wafer fabrication process is the Radiation-Hard, Oxide-Walled, Self-Aligned Emitter (ROSE) process.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115326498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MCS 2 Program provides for the evolutionary development of an automated command, control and communications system utilizing a mix of commercial-off-the-shelf (COTS) equipment to take advantage of current commercial technologies and to rapidly develop the products necessary for interfaces. Using existing commercial technologies, BDM has developed two interface devices for tactical communications systems, the Single Channel Interface (SCI) and the DCCS Communications Interface Unit (DCIU). The SCI provides a simple interface between the computer and any one of the following Army communications means: single channel FM radio, (secure and non-secure), multichannel radio, and wireline. The DCIU is a microprocessor controlled multiple channel communications interface unit. It provides interfaces to the same communications means as the SCI as well as an RS-232 interface. In addition, it permits a single host computer to monitor three communications nets simultaneously, in both a send and receive mode.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125281651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We consider relatively fast frequency hopping with hopping rate of 1 KHz, and 127 different hopping frequencies. We assume that any two hopping frequencies propagate via statistically independent channels, i.e. via channels with statistically independent time and frequency spreading and statistically independent delay times. Also according to the measurement results we assume that the maximum deviation of the delay time from the nominal delay time is 1 msec and is uniformly distributed around the nominal delay time. For such a case we propose an acquisition scheme whose characteristics are analyzed mathematically and by computer simulation.","PeriodicalId":126184,"journal":{"name":"MILCOM 1986 - IEEE Military Communications Conference: Communications-Computers: Teamed for the 90's","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126928573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
