Bridging Spatial Modulation With Spatial Multiplexing: Frequency-Domain ESM

IEEE Journal of Selected Topics in Signal Processing, 2019
Spatial modulation (SM) is a multi-input multi-output (MIMO) technique, which was originally introduced to reduce the number of radio frequency (RF) chains in a MIMO transmitter and thereby reduce cost and power consumption. Although it is very appealing in theory, this concept actually has two main problems: The first is that SM involves antenna ...

The Spatial and Frequency Domains

2009
The interconversion between spatial and frequency domains using Fourier and other transforms is of critical importance in image processing and, for some imaging methods, the construction of images from raw scan data. A significant feature of the transforms is that we can convert back and forth between spatial and frequency domains without loss of ...

Geo-spatial Domain Expertise in Microblogs

2014
In this paper, we present a framework for describing a user's geo-spatial domain expertise in microblog settings. We investigate a novel way of casting the expertise problem by using points of interest POI as a possible categorization of expertise. To this end, we study a large-scale sample of geo-tagged tweets and model users' location tracks in order

Spatial domain LiDAR

2020
This document presents the work developed on the scope of a master thesis on “Spatial domain LiDAR”. The goal of this project is to explore an alternative path to mainstream LiDARs based on time-of-flight. The alternative path consists in illuminating a scene with a dot matrix, estimating the distance to each dot via triangulation.

A comprehensive review of approaches for spatial domain recognition of spatial transcriptomes

Briefings in Functional Genomics
Abstract In current bioinformatics research, spatial transcriptomics (ST) as a rapidly evolving technology is gradually receiving widespread attention from researchers. Spatial domains are regions where gene expression and histology are consistent in space, and detecting spatial domains can better understand the organization and ...
