— In Orthogonal Frequency Division Multiplexing (OFDM) systems, synchronization errors in the receiver cause a linear phase rotation at the output of the Discrete Fourier Transfo...
Abstract--Assuming imperfect channel estimation, we propose an improved detector for orthogonal frequency-division multiplexing (OFDM) systems over a frequency-selective fading cha...
A phase synchronizationmethod, which provides non-uniform frequency offset compensation needed for wideband OFDM [1], is coupled with low-complexity channel estimation in the time...
- An initial timing offset estimation method for orthogonal frequency-division multiplexing (OFDM) systems is proposed. Conventional preamble-based synchronization methods result i...
Orthogonal Frequency Division Multiplexing (OFDM) has been adopted in many broadband wireless communication standards. In OFDM systems, channel estimation is a crucial module in co...
