In the present work, design and Field Programmable Gate Array (FPGA) implementation of a new Adaptive Post detection Integration (API) algorithm, designated as Conditioned Adaptive Post detection Integration (C-API), is proposed. The proposed C-API algorithm overcomes the problem of azimuth resolution degradation in the traditional API, especially for high signal to noise ratios (SNRs), and gives...
Recently, maximum power point trackers (MPPTs) that based on single variable (IPV or VPV) have a great attention. That is due to their simplicity and easiness in implementation, when compared to the other tracking techniques. In this paper, two methods have been proposed to design a variable step size MPPT using only a single current sensor for stand-alone battery storage PV systems. These methods...
Binary detection integrator is characterized by its simplicity, resistance against asynchronous interference, and its good detection performance. It suffers from detection loss due to non-homogeneous background. To overcome the limitations of binary integration, the Adaptive Binary Integrator (ABI) is used. ABI achieves the advantages of automatic detection and adaptive thresholding over the binary...
Real-time face recognition by computer systems is required in many commercial and security applications since it is the only way to protect privacy and security. On the other hand, face recognition generates huge amounts of data in real-time. Filtering out meaningful data from this raw data with high accuracy is a complex task. Most of the existing techniques primarily focus on the accuracy aspect...
Square root is one of the fundamental arithmetic operations in signal and image processing algorithms. This article presents a novel pipelined architecture to implement N-bits fixed point square root in FPGA using non-restoring algorithm. Pipelining hazards were avoided by modifying the non-restoring algorithm resulting in a 30% improved latency time. Furthermore, the proposed architecture is flexible...
Eigen values evaluation is the fundamental part usually for real-time pattern recognition applications but computational intensive. Numerically calculated Eigen values based on floating point operations induce errors due to rounding and truncation effects, and the error increases further when fixed point operations are involved. On the other hand, fixed point operations are time efficient for hardware...
This paper presents a reduced-complexity, fixed- point algorithm and efficient VLSI architecture implemented on FPGAs for direct matrix inversion (DMI) beamforming technique for code division multiple access (CDMA) systems equipped with antenna arrays. In this paper, we re-design the direct matrix inversion, wherein a steepest descent method is used to solve the matrix inversion problem in an iterative...
