The Maximum Power point Tracking Controller (MPPT) is an essential part of the photovoltaic (PV) system, it is used to extract the maximum power from the photovoltaic solar module and transfer that power to the load. Several MPPT techniques have been proposed in the literature. One of the most commonly used techniques is the perturb and observe algorithm (P&O), due to its low cost and simple implementation,...
This paper concerns a new and powerful Low-Density Parity-Check (LDPC) stochastic decoding algorithm, called Controlled Start-up Stochastic (CSS) decoding, to implement fully parallel LDPC decoders. The proposed algorithm uses a clever starting point computing method to improve the convergence as well as to reduce the latency of the decoding process, without a significant hardware complexity cost...
This paper presents an OCR method for degraded character recognition applied to typewritten document produced by typesetting machine. The complementary similarity measure method (CSM) is a well known classification method and widely applied in the area of character recognition. In this work the CSM method is not only used as a classifier but also introduced as a feature extractor, and applied to degraded...
This paper presents new VLSI architectures for finite impulse response (FIR) filters and discrete wavelet transform, intended for very high-speed signal and image processing. The proposed architectures, based on combining pipeline and parallel arithmetic methods, provide a new and very fast convolution approach with a reduced critical path. The key to this is a clever use of D-latches and multipliers...
