An Efficient LUT Design on FPGA for Memory-Based Multiplication
An efficient Lookup Table (LUT) design for memory-based multiplier is proposed. This multiplier can be preferred in DSP computation where one of the inputs, which is filter coefficient to the multiplier, is fixed. In this design, all possible product terms of input multiplicand with the fixed coefficient are stored directly in memory. In contrast to an earlier proposition Odd Multiple Storage ...
متن کاملAn efficient codebook design in SDCHMM for mobile communication environments
Speech recognition systems require too much memory to run and are too slow for mass application. In order to overcome these constraints and make speech recognition systems suitable for mobile devices, we propose efficient codebook construction method for subspace distribution clustering hidden markov modeling (SDCHMM). The output probability of mixture Gaussians is more sensitive to quantizatio...
متن کاملSCMA with Low Complexity Symmetric Codebook Design for Visible Light Communication
Abstract—Sparse code multiple access (SCMA) is attracting significant research interests currently, which is considered as a promising multiple access technique for 5G systems. It serves as a good candidate for the future communication network with massive nodes due to its capability of handling user overloading. Introducing SCMA to visible light communication (VLC) can provide another opportun...
متن کاملAn Efficient and Effective Method for VQ Codebook Design
Although there have been many methods proposed to speed up the VQ codebook generation process, it turns out to be the case that these methods either suffer from slight degradation in overall distortion or just maintain the same quality with hardly time saving. In other words, the methods proposed to generate better codebooks are often inefficient, and those which are fast tend to have worse qua...
متن کاملAn Efficient Algorithm for Codebook Design in Transform Vector Quantization
In this paper, a new wavelet-domain codebook design algorithm is proposed for image coding. The method utilizes mean-squared error and variance based selection schemes for good clustering of data vectors in the training space. As the clustering process terminates only in two steps, it is highly computationally efficient as compared to other reported methods. Simulation results are presented to ...
