Ultrasonic Sensor for Mobile Mini-Robots Using Pseudo-Random Codes
Ultrasonic sensors enable mobile autonomous systems to obtain information about obstacles in large environments. In the presented work, taking the limited energy resources of a mobile robot into account, only one transmitter is used. The employment of two receivers permits the calculation of the distance and direction of objects. Using pseudo-random sequences, simultaneously transmitting and re...
متن کاملDigital Radio Mondiale ( DRM ) DIGITAL RADIO MONDIALE DRM LOCAL COVERAGE USING THE 26 MHz BROADCASTING BAND
This document reports on a carefully designed set of fixed and mobile reception tests in Mexico City on the DRM (Digital Radio Mondiale) system at a frequency in the uppermost shortwave broadcasting band – around 26 MHz – for local broadcasting. The testing was done during July 2005. These were not operational tests; that is, neither the transmitter antenna, nor antenna location, nor transmitte...
متن کاملRandom Codes for Digital Fingerprinting
Unlicensed, or illegal, copying of data is a problem in many areas. Despite various efforts in copy protection and copyright enforcement (both legal and technical), the problem still exists, and with the growing use of digital means of storing and distributing data the problem seems to be getting worse. Storing a unique, invisible marking in each distributed object is a possible way of dealing ...
متن کاملTechnical Advances in Digital Audio Radio Broadcasting
The move to digital is a natural progression taking place in all aspects of broadcast media applications from document processing in newspapers to video processing in television distribution. This is no less true for audio broadcasting which has taken a unique development path in the United States. This path has been heavily influenced by a combination of regulatory and migratory requirements s...
متن کاملOn Radio Broadcasting in Random Geometric Graphs
One of the most frequently studied problems in the context of information dissemination in communication networks is the broadcasting problem. In this paper we consider radio broadcasting in random geometric graphs, in which n nodes are placed uniformly at random in [0, √ n], and there is a (directed) edge from a node u to a node v in the corresponding graph iff the distance between u and v is ...
