It is well-known that the OFDM scheme has some tolerance for symbol/frame timing errors (i.e. valid starting position of FFT window). Such tolerance exist for SC-FDE. However, frame timing offset affects the receiver performance due to deviation in frequency domain channel estimation result when fractional channel estimation vector is applied in time domain. To achieve optimized receive performance...
Channel estimation based on two-dimensional discrete- time Fourier transform interpolation (2D-DFTI) is suitable for orthogonal frequency division multiplexing (OFDM) systems because of its robustness to doubly-selective fading channels and high computational efficiency. However, its performance will degrade significantly for packet OFDM systems with virtual subcarriers due to the Gibbs phenomenon...
