Empowering 'Ambient Intelligence' with a Direct Sequence Spread Spectrum CDMA Positioning System

چکیده
Distributed intelligence is set to revolutionise the interface between humans and the surrounding environment. Smart objects will become more and more commonplace in the home of the next decade, in a dynamic network of distributed intelligent elements. One of the most important steps yet to be addressed in this vision is a positioning system able to locate people and objects and allow them to interact in an efficient way. This paper presents an experimental 2.4 GHz Direct Sequence Spread Spectrum system for accurate indoor positioning. The theoretical limits of this technology are presented along with the challenges ahead in delivering the location results with clear and userfriendly logical descriptors.

CDMA – Code Division Multiple Access
Code Division Multiple Access (CDMA) is probably the most interesting multiple access method provided by spread spectrum technology. CDMA refers to a multiple access method in which the individual terminals use spreadspectrum techniques and occupy the entire spectrum whenever they transmit. This paper focuses on direct-sequence spread-spectrum principles (processing gain, spreading, de-spreadin...

In this work a preliminary study for identifying the transmission modes in a software radio (SR) based wireless terminal for ambient intelligence application is presented. In particular, the context is the identification of the presence of two communications mode as Bluetooth Personal Area Network (PAN) based on Frequency Hopping (FH) air interface, and IEEE WLAN 802.11b based on Direct Sequenc...
متن کاملA Study and Design of Direct Sequence Code Division Multiple Access (ds-cdma) Transceiver
This paper addresses CDMA transceiver using direct sequence spread spectrum and includes real time signal processing for scrambling of spread spectrum signal, and descrambling the signal at the receiver using the same pseudo-random code. The simulation of the entire DS-CDMA transceiver system has been implemented using MATLAB, which provides real time audio input to the system.
متن کاملIntelligent CDMA systems
Direct-sequence Code-division multiple-access (DS-CDMA) has emerged as proper format for communication systems. As a result of multiple-access interference (MAI), inter-symbol interference (ISI), narrowband interference (NBI) and nonlinearities in channels, DS-CDMA systems can suffer deterioration in performance . New techniques to suppress narrow-band and multiple-access interference for sprea...
