The development of radar technology has always been a hot issue. In recent years, due to the popularization of Advanced Driver Assistance Systems (ADAS), such as autonomous driving system and collision avoidance system, the requirements for radar tec

We use FFT-based convolution in frequency domain to reduce computational complexity in CNNs. The properties of conjugate symmetry and down-sampling is adopted to further reduce complexity. By eliminating filter weights in CNNs that can save computati

Based on an error-flattened, non-uniform-region linear-approximation algorithm, this brief proposes a low-error and a cost-efficient design procedure for realizing an optimized shift-and-add Logarithmic Unit (LU), which uses minimum hardware to meet

The min-sum algorithm is the most common method to simplify the belief-propagation algorithm for decoding low-density parity-check (LDPC) codes. However, there exists a performance gap between the min-sum and belief-propagation algorithms due to nonl

In this paper, we adopt a restricted Gaussian elimination on the Hankel structured augmented syndrome matrix to reinterpret an early stopped version of the Berlekamp–Massey algorithm in which only $(t + e)$ iterations need to be performed for the d

This paper presents the multirate and re-sampling techniques to realize a low-delay, 18-band quasi-ANSI filter bank for digital hearing aids, which not only achieves a rather low computation complexity without a significant increase in the latency, b

An efficient implementation of a parallel version of the Feng-Rao algorithm on a one-dimensional systolic array is presented in this paper by adopting an extended syndrome matrix. Syndromes of the same order, lying on a slant diagonal in the extended

In this paper, a dynamic normalization technique is proposed to approximate the nonlinear operation in decoding LDPC codes. The criterion in determining the normalization factor is also presented with theoretical analysis. The proposed method improve

Spatial data clustering plays an important role in numerous fields. Data clustering algorithms have been developed in recent years. K-means is fast, easily implemented and finds most local optima. IDBSCAN is more efficient than DBSCAN. IDBSCAN can al

This paper presents a novel technique to reduce the area of the hardwired lookup table (LUT) of DA-based FIR filters. It explores the optimal quantization on the real-valued LUT with optimal global scaling and error distribution, and we apply an effe
