Orthogonal frequency division multiplexing (OFDM) is an important technology for high-speed data transmission by virtue of its high spectral efficiency and robustness to multipath fading. These advantages can be achieved only with good synchronization both in time and frequency domain. For time synchronization, the cross-correlation based scheme can be combined with autocorrelation one to mitigate...
The stack algorithm is a promising tree-search algorithm with relatively low computation complexity for multi-input multi-output (MIMO) systems. Recent researches show that it obtains low detection complexity at the price of performance degradation. To achieve a better compromise between computational complexity and detection performance, a sphere constraint stack detection algorithm (SC-Stack) is...
