A Very High Throughput Deblocking Filter for H.264/AVC
Journal of Signal Processing Systems - Tập 73 - Trang 189-199 - 2013
This paper presents a novel hardware architecture for the real-time high-throughput implementation of the adaptive deblocking filtering process specified by the H.264/AVC video coding standard. A parallel filtering order of six units is proposed according to the H.264/AVC standard. With a parallel filtering order (fully compliant with H.264/AVC) and a dedicated data arrangement in local memory ban......
GPGPU Based Parallel Implementation of Spectral Correlation Density Function
Journal of Signal Processing Systems - Tập 92 - Trang 71-93 - 2019
In this study, the parallelization of a critical statistical feature of communication signals called the spectral correlation density (SCD) is investigated. The SCD is used for synchronization in OFDM-based systems such as LTE and Wi-Fi, but is also proposed for use in next-generation wireless systems where accurate signal classification is needed even under poor channel conditions. By leveraging ......
Dynamic Resource Allocation in Non-orthogonal Multiple Access Using Weighted Maximin Fairness Strategy for a UAV Network
Journal of Signal Processing Systems - Tập 92 - Trang 1397-1406 - 2020
Non-orthogonal multiple access (NOMA) with power domain multiplexing and successive interference cancellation (SIC) is one of the promising technologies for future wireless communication. The performance of NOMA is highly dependent on resource allocation such as power allocation and channel assignment. In this paper, we investigate the power allocation (PA) scheme, to optimize the weighted maximin......

Online Acoustic System Identification Exploiting Kalman Filtering and an Adaptive Impulse Response Subspace Model
Journal of Signal Processing Systems - Tập 94 - Trang 147-160 - 2022
We introduce a novel algorithm for online estimation of Acoustic Impulse Responses (AIRs) which allows for fast convergence by exploiting prior knowledge about the fundamental structure of AIRs. The proposed method assumes that the variability of AIRs of an acoustic scene is confined to a low-dimensional manifold which is embedded in a high-dimensional space of possible AIR estimates. We discuss v......
Efficient Spatially-Variant Single-Pixel Imaging Using Block-Based Compressed Sensing
Journal of Signal Processing Systems - Tập 93 - Trang 1323-1337 - 2021
Single-pixel imaging is an important alternative to conventional camera. Only a single-pixel detector is needed to capture image data by measuring the correlation of the target scene and a series of sensing patterns. Conventionally, Nyquist-Shannon theorem requires measurements not less than the image pixels for an error-free reconstruction. Compressed sensing (CS) enables image reconstructions wi......
A Hardware-Efficient Method for Extracting Statistic Information of Connected Component
Journal of Signal Processing Systems - Tập 88 - Trang 55-65 - 2016
The statistic information of connected components are fundamental for image processing, which could be acquired through connected components labeling. This paper proposes a hardware-efficient method for extracting statistic information of connected components in a binary image to accelerate image processing in embedded application. The proposed method scans two adjacent rows with 2 × 2 template si......
