Spectrum-Efficient Coherent Photonic Terahertz Transmission System Based on Subcarrier Multiplexing With Offset Quadrature Amplitude Modulation

open access: yesIEEE Photonics Journal
To overcome the spectral efficiency (SE) limitations of conventional subcarrier multiplexing (SCM) caused by guard bands, a spectrum-efficient coherent photonic terahertz (THz) transmission system based on SCM with offset quadrature amplitude modulation (

Joint Symbol Timing and CFO Estimation for OFDM/OQAM Systems in Multipath Channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
The problem of data-aided synchronization for orthogonal frequency division multiplexing (OFDM) systems based on offset quadrature amplitude modulation (OQAM) in multipath channels is considered. In particular, the joint maximum-likelihood (ML) estimator
