A robust asynchronous multiuser STBC-OFDM transmission scheme for frequency-selective channels
Abstract--In this paper, we propose a robust STBC transmission scheme to combat timing synchronization errors over frequency-selective multiple-access channels. We start by derivin...

Identification of clock synchronization errors: A behavioral approach
Abstract-- The subject area of this paper is discrete-time linear time-invariant systems composed of subsystems whose state updating is asynchronous due to the clock signal arrivin...

Improved Channel Estimation in OFDM Systems with Synchronization Errors and Back-Off
— 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...
