System and method for near optimal joint channel estimation and data detection for cofdm systems

摘要: Joint channel estimation and maximum likelihood decoding method for Coded Orthogonal Frequency Division Multiplexing (COFDM) systems are presented. Using this in conjunction with convolutional coding, robust nearly optimal coherent detection can be achieved rapid dispersive fading channels. Significant performance gain packet data throughput is realized a system aggressive frequency reuse. A estimating characteristics multicarrier transmission comprising means receiving signal, applying Fast Fourier transformations to the of over which signal was transmitted using iterative processing transformed Also presented steps combination backward processing, signal.
