Feasibility of Adaptive Transmission for Multicarrier and Frequency Hopping Mobile Radio Systems

Category: Software and Web Development, Networking and Communications

Overview This paper addresses feasibility of adaptive transmission for rapidly varying fading channels encountered in mobile communication systems. Due to rapid channel variations and the feedback delay, implementation of adaptive transmission in these channels requires accurate prediction of future channel conditions. The paper describes the design and performance of adaptive transmission methods enabled by the Long Range Fading Prediction algorithms (LRP) for Orthogonal Frequency Division Multiplexing (OFDM) and slow Frequency-Hopping Spread Spectrum (FH/SS) systems. The LRP algorithms are tested with a modified Jakes model and the realistic physical model. To enable channel loading for Adaptive OFDM (AOFDM), robust adaptive prediction methods that track channel parameter variations are developed and compared.
