A -- DEVELOPMENT OF A WIDEBAND CHANNEL SIMULATOR SOL DSWA01-98-R-0042 POC Michelle Gerenyi, Negotiator, (703) 325-1190, Edward Archer, Contracting Officer, (703) 326-8506 The Defense Special Weapons Agency (DSWA) is seeking contractors with the capability to design and develop a wideband channel simulator. This simulator is to be based upon state-of-the-art digital signal processing technology that will allow it to simulate the expected range and types of nuclear and naturally disturbed channel parameters critical to ensuring that current and future DoD satellite communications systems perform properly. DSWA seeks a modular design approach that will provide the capabilities of flat fading with frequency selective fading in one simulator. Additional properties include selectable amounts of delay spread, Total Electron Content (TEC) effects and other specified nuclear effects. A modular design approach will allow for an expandable system. The base model is assumed to be a multi-channel simulator. A modular design would allow additional capabilities to be added later as they were needed. The interface between the simulator and the communications device (modem) will be an important part of the simulator. Since many different communications systems will need to be tested, (such as the Universal Modem System, Milstar, and the Global Positioning System) the simulator must be able to handle live signals from the UHF through EHF bands. Many of these systems also use frequency hopping and it can not be assumed that a de-hopped signal will always be available. A versatile interface will allow testing over a wide range of systems. This is an unrestricted procurement. All requests for the RFP must be in writing. Faxed requests are acceptable and should be faxed to the attention of Michelle Gerenyi at (703) 325-9291. If the request is faxed, no hard copy is required. Acquisition Management has added "Procurement Opportunities" to the DSWA Home Page available on the World Wide Web. Information will include this synopsis and more. Please check us out at www.dswa.mil. Reference Synopsis No. 98-138 Posted 08/13/98 (I-SN236565). (0225)
