An adaptive OFDM system for dynamic wireless communications using real-time link status monitoring and long range channel prediction
EF 2012-13
Résumé
The nature of future broadband wireless communications is very dynamic, due partly to the possible fast variation of wireless channels, and partly to the wide range of user applications and diverse requirements from recent advent of mobile applications. Architecture and parameters of conventional communications systems are designed statically based on a ""worst case"" of all expected communications scenarios. Without considering the dynamic nature of channel conditions and user requirements, the static design approach often leads to a very inefficient usage of the communications resources when the system operates at improved channel conditions or reduced data traffic.
An adaptive Orthogonal Frequency Division Multiplexing (OFDM) system, using a precoded cyclic prefix (PCP) enabled control channel for dynamic adaptation, has been proposed by the applicant to improve the efficiency of future wireless communications. The new dynamic OFDM system is based on the concurrent transmission of communication data together with the transmission system parameters and system adaptation information using just one OFDM signal.
The primary goal of the proposed NSERC Collaborative Research and Development (CRD) project is to develop all the necessary enabling techniques for the PCP-OFDM system including wireless link status monitoring, long range channel predication, fast rate adaptation and data stream aggregation for a Wi-Fi based prototype implementation and technology transfer to our industry partner TELoIP. Specific objectives of the NSERC CRD project include: (a) Development of reliable link status monitoring and long term channel predication algorithms; (b) Design of computational efficient rate adaptation strategy to achieve dynamic link adaptation with minimal delay for PCP-OFDM system in the context of wireless aggregation solution from TELoIP; (c) Integration of developed channel predication, rate adaptation, and PCP-OFDM system on the TELoIP platform; and (d) Test, evaluation and enhancement of the Wi-Fi prototype.
