—In this paper, the paradigm of sphere decoding (SD) for solving the integer least square problem (ILS) is revisited, where extra degrees of freedom are introduced to exploit the decoding potential. Firstly, the equivalent sphere decoding (ESD) is proposed, which is essentially the same as the classic Fincke-Pohst…

—This paper discusses the problem of extracting spread spectrum hidden data from the perspective of lattice decoding. Since the conventional blind extraction scheme multicarrier iterative generalize least-squares (M-IGLS) and non-blind extraction scheme minimum mean square error (MMSE) suffer from performance…

—Convolutional precoding in polarization-adjusted convolutional (PAC) codes can reduce the number of minimum weight codewords (a.k.a error coefficient) of polar codes. This can result in improving the error correction performance of (near) maximum likelihood (ML) decoders such as sequential decoders and sphere…

'Youming Sun' 'Xiangcheng Li'] The sphere decoding (SD) algorithm can provide (sub)optimal solutions with reduced computational complexity of maximum likelihood (ML) detection for multi-input multi-output (MIMO) communication systems. In this paper, we propose a novel low complexity symmetric-coded based SD algorithm…

Communications: Low Error Rate, Low Latency, and Low Power Consumption Authors: ['Donghwa Han' 'B. G. Lee' 'Min Seong Jang' 'Donghun Lee' 'Seho Myung' 'Namyoon Lee'] Abstract—Block orthogonal sparse superposition (BOSS) code is a class of joint coded modulation methods, which can closely achieve the finite-blocklength…

We present an innovative intracortical Brain-Computer Interface (BCI) to bridge the gap between laboratory settings and real-world applications. This BCI approach introduces three key advancements. First, we utilized neural signals from three macaque brain regions – primary motor, dorsal and ventral premotor cortex –…

Multi-User MIMO (MU-MIMO) detection plays a pivotal role in modern wireless receivers, yet practical downlink deployments are severely bottlenecked when co-scheduled users employ unknown and highly heterogeneous modulation formats. This paper introduces a joint architecture that seamlessly integrates blind modulation…

—A genie-aided decoder for finite dimensional lattice codes is considered. The decoder may exhaustively search through all possible scaling factors α ∈ R. We show that this decoder can achieve lower word error rate (WER) than the oneshot decoder using αMMSE as a scaling factor. A lower bound on the WER for the decoder…

Scope: I introduce a reproducible, closed-surface mapping of the periodic system onto a sphere with a single equatorial ring, yielding a symmetric alternative to 2D layouts. The construction partitions the sphere into belts that match the cardinalities of the s/p/d/f blocks (2/6/10/14), places lanthanoids and actinoids…

In close-range monocular visual measurement and cooperative target pose estimation, conventional planar targets are constrained by viewpoint changes and are prone to perspective distortion. Although spherical targets provide omnidirectional observability, their PnP-based pose estimation may still suffer from large…

Imaging based spatial transcriptomics technologies such as MERFISH have opened new avenues for studying cellular organization and gene expression within intact tissues. However, the accuracy of downstream analyses depends critically on the decoding step that reconstructs barcodes from fluorescence patterns and maps…

'Janis Nötzel' 'Fred Fung' 'Maximilian Schädler' 'Aleksey Fedorov'] Nearest-neighbour clustering is a simple yet powerful machine learning algorithm that finds natural application in the decoding of signals in classical optical-fibre communication systems. Quantum k-means clustering promises a speed-up over the…

Group-equivariant neural networks have emerged as a data-efficient approach to solve classification and regression tasks, while respecting the relevant symmetries of the data. However, little work has been done to extend this paradigm to the unsupervised and generative domains. Here, we present Holographic-(V)AE…

X-ray Computed Tomography (CT) is a non-invasive, non-destructive approach to imaging materials, material systems and engineered components in two- and three- dimensions. Acquisition of 3D images requires the collection of hundreds or thousands of through-thickness X-ray radiographic images from different angles. Such…

Accurate recognition of hand-drawn chemical structures is crucial for digitising hand-written chemical information found in traditional laboratory notebooks or for facilitating stylus-based structure entry on tablets or smartphones. However, the inherent variability in hand-drawn structures poses challenges for…
