A novel iterative symbol detection of OFDM systems in time and frequency selective channels

When orthogonal frequency division multiplexing (OFDM) technology is applied in time- and frequency-selective, or doubly selective channels, the time-variant character of the channel destroys subcarrier orthogonality, resulting in inter-carrier interference (ICI). In general, the classical OFDM detection algorithms are neither effective to mitigate the ICI… CONTINUE READING
