Abstract :
In this paper, we study joint channel estimation and maximum likelihood decoding method for coded orthogonal frequency division multiplexing (COFDM) systems. Using this method in conjunction with convolutional coding, robust and nearly optimal coherent detection can be achieved in rapid dispersive fading channels. Significant performance gain in packet data throughput is realized in a system with aggressive frequency reuse
