Design And Implementation Of Wide Band Compaction System Based On The Noise FM

In recent years, with the development of wireless communication technology, the livingenvironment of people was improved greatly. It also can be exploited by the lawbreakers touse radio harming for technical innovations. Therefore, it is an urgent event to create a safeand reliable communication environment with strict control of non-standard communicationchannels.This paper is based on the design and implementation of Compaction system based onthe noise FM. By using the modular design concept, we design a new system of suppression.In section one this paper describe the signal generation of FM noise suppress as well as itssuperiority, Multichannel broadband segment suppress interference technology, Digitalconversion and other related theories. The second part describes the basic principles of theDDS frequency synthesizer. After a detailed analysis of system suppression and overall designwill be presented. The main requirement of this article is to determine the system hardwarecomponents block diagrams and implementation of brief system module design. After on thebasis of the reliability of system and resource utilization we propose a new DDS core design.Our system also include broadband blocking aiming swept three pressing manner. To achieveintermediate frequency signal, by the implementing upper conversion processing andspectrum move the new DDS core design is further implemented on the FPGA chip. Finally tocheck the system performance, we perform debugging and verification of this repressionsystem. The paper mainly focuses on the newly implemented soft suppression system that isimplemented in hardware design.The design uses a modular design concept. It includes the power supply module, thebaseband signal modules, the core signal processing module, upconversion, power amplifierand antenna. The design of baseband noise signal Zener diode breakdown generated by thefront-end tuning enlarge sample sent to DDS processing, and then through the high-speed DAand analog upconversion process, the final amplifier will power the signal and sent to transmitantennas. Through experimental testing, the system is designed to meet the designrequirements of cheating signal compaction.
