Efficient Implementation of Digital Receiver on FPGA
There is a boast demand for wireless communication technology in present days. All the new wireless technologies are communicated by the Digital receiver. The main aim of this receiver is obtain information from target devices, after receiving information the parameters like speed, distance and angle of target device are calculated in Radars. In this paper introduced a 70 MHz Digital receiver w...
متن کاملDesign and Simulation of a Modified 32-bit ROM-based Direct Digital Frequency Synthesizer on FPGA
This paper presents a modified 32-bit ROM-based Direct Digital Frequency Synthesizer (DDFS). Maximum output frequency of the DDFS is limited by the structure of the accumulator used in the DDFS architecture. The hierarchical pipeline accumulator (HPA) presented in this paper has less propagation delay time rather than the conventional structures. Therefore, it results in both higher maximum ope...

متن کاملDevelopment System for FPGA-Based Digital Circuits
The paper discusses some new hardware and software tools that can be used for the design of virtual circuits based on dynamically reconfigurable FPGAs. With the aid of these tools we can implement a system that requires some hardware resources Rc, on available hardware that has resources Rh, where Rc>Rh. The main idea of the approach supported by these tools is the rational combination of FPGA ...
متن کاملThe Design of Radar Digital Intermediate Frequency Test System
To satisfy the requirement of high performance signal processing technique, it is necessary to use the direct sampling of intermediate frequency signal to obtain quadrature signals. Digital intermediate frequency (DIF) system is widely used in radar and communication system. This paper briefly introduces the principle of test system based on DIF. We design this DIF test system to test the perfo...
