Orthogonal time frequency space modulation (OTFS) scheme establishes reliable communication in a rapidly time-varying wireless channel with a high Doppler spread.
We consider nonlinear zero-forcing (ZF) precoding based dynamic spectrum management for improving the G.fast peak-rate performance when only a few users in the cable binder are active.
We consider nonlinear zero-forcing (ZF) precoding design to improve the downstream G.fast peak-rates when only a few users in the cable binder are active.
We propose a low-complexity coding scheme that is resilient against sporadic phase slip events and based on a new phase-slip transparent construction of LDPC codes, called block-symmetric codes.
We propose a new and low-complexity 4D-signaling that ensures polarization-multiplexed systems to be robust against polarization dependent loss.
High peak to average power ratio (PAPR) is a particular disadvantage of orthogonal frequency division multiplexing (OFDM) systems and can significantly degrade the power efficiency at the transmitt
In TDD reciprocity-based massive MIMO it is essential to compute the downlink precoding matrix over all OFDM resource blocks within a small fraction of the uplink-downlink slot duration.
For short and medium reach network applications, a low-cost and high performance integrated laser-electroabsorption modulator source for 1.5 mu m transmissions is proposed.

A novel low-cost photoreceiver that combines an erbium-doped waveguide amplifier (EDWA) and a packaged short planar multimode waveguide PIN photodiode has demonstrated -21.2 dBm sensitivity at BER
