A target simulator based on the digital RF memory (DRFM) is presented in this paper. The simulator consists of a interface unit which is controlled by MCU, a high-precision calculation DSP unit, a DRFM unit based on FPGA, and corresponding microwave unit. This target simulator has simple circuits, high precision and stability. The integrated testing results with a seeker proved that the system successfully...
A method for mapping an algorithm, which is represented by the loop nest into the application specific structure is proposed. The method consists in translating the loop nest into the tensor equation. The tensor equation represents a set of structural solutions. The optimized solution finding consists in solving this equation in integers. The proposed limitations to the parts of the tensors help to...
The noise simulation circuit of noncoherent spread-spectrum system intermediate frequency (IF) signal simulator is designed based on FPGA and DSP. This circuit generates white Gaussian noise (WGN), calculates coefficients of signal-to-noise ratio (SNR) refer to the specified SNR of each channel and according to these coefficients to generate spread-spectrum IF signal for transmitting to simulate the...
Nowadays, most digital control for motion and power electronics systems are based on DSPs. This paper presents a FPGA-based digital control for a DC-DC converter. The main difference from DSP-based solution is that FPGA allows simultaneous execution of all control procedures, enabling high performance and novel control methods. The control algorithm has been developed using a VHDL language or CAD...
The demands of modern applications for ever increasing performance for real-time simulations have posed considerable challenges to simulation developers which are still not fully met. An effective response to these challenges has involved an interesting combination of a return to old-style programming techniques such as multi-rate simulation and low-level program design with a focus on individual...
Digital signal processing (DSP) algorithms exhibit an increasing need for the efficient implementation of trigonometric functions, coordinate transformations or rotations of complex valued phasors. Popular application examples are algorithms used in digital communication technology and in adaptive signal processing. The trigonometric functions like cosine and sine form the building block of certain...
Two new methods to improve the ultra-low speed control performance of ac servo system are described in this paper. One is improved M/T method, which could minimize the influence of speed detection dead time and smooth the measurement. Another is instantaneous speed detection based on constant jerk model, which assumes the rotor jerk is constant at the interval of sampling period. The instantaneous...
