Robust Wireless Communication for Multi-Antenna, Multi-Rate, Multi-Carrier Systems
Today’s trend of migrating radio devices from hardware to software provides potentials to create flexible applications for both commercial and military use. However, this raises security concerns, as malicious attacks can also be alleviated to break legitimate communications. In this research work, we study and build practical systems to mitigate the impact of some serious jamming threats: high...
متن کاملDiscrete Multi-Tone and Filtered Multi-Tone Architectures for Broadband Asynchronous Multi-User Communications
Multi-carrier systems based on both discrete multi-tone and filtered multi-tone architectures are investigated for application to asynchronous multi-user communications. Multiplexing of users is implemented by assigning a sub-set of the available carriers to each user. Communications are asynchronous, meaning that the signals belonging to distinct users propagate through independent frequency s...
متن کاملPhotonic-Based RF Transceiver for UWB Multi-Carrier Wireless Systems
In this paper an all-optical system exploitable as the core structure for a photonic-based RF transceiver is presented. The proposed scheme is able to simultaneously perform either upor down-conversion of multiple frequency Ultra-Wide Band (UWB) RF signals, employing a single Mode-Locking Laser (MLL). The system has been experimentally demonstrated and tested by upand down-converting orthogonal...
متن کاملMulti-carrier Transmission Techniques for Wireless Communication Systems: A Survey
The next generation wireless communications systems require higher data rates transmission in order to meet the higher demand of quality services. Research in wireless digital communications techniques have been expending very rapidly in the last few decades, resulting more reliable wireless communication systems that operate at higher spectral efficiency. Since there have been an increased in ...
متن کاملSimulation of Multi-Carrier CDMA system for future wireless systems
Abstract In this paper, new multiple access schemes based on the combination of Code Division Multiple Access (CDMA) and Multicarrier modulation (also known as OFDM (Orthogonal Frequency division Multiplexing)) are reviewed. Some of the main systems proposed to date are identified and the advantages of such systems discussed. A description of a simulation platform developed to analyse the perfo...
