Abstract-- We address low-complexity, highly-accurate frequency offset estimation for MB-OFDM-based UWB systems. We discuss unique characteristics of the MB-OFDM systems, namely, d...
Abstract— This paper discusses channel estimation in a cooperative orthogonal frequency-division multiplexing (OFDM) network in the presence of frequency offsets. Both the amplif...
Abstract—A frequency offset compensation method for OFDMFDMA, that can correct offsets after the DFT via circular convolution, is proposed as an alternative to the direct method ...
