Comparison of CP-OFDM and OFDM/OQAM in Doubly Dispersive Channels
In this paper we compare the performance of cyclic prefix based OFDM (CP-OFDM) systems and OFDM/offset QAM (OFDM/OQAM) systems in doubly dispersive channels, by investigating the...

Minimum BER beamforming in the RF domain for OFDM transmissions and linear receivers
In this paper, we study transmission schemes for a novel OFDMbased MIMO system which performs adaptive signal combining in radio-frequency (RF). Specifically, we consider the prob...
