Comb-based WDM transmission at 10 Tbit/s using a DC-driven quantum-dash mode-locked laser diode
Chip-scale frequency comb generators have the potential to become key building blocks of compact wavelength-division multiplexing (WDM) transceivers in future metropolitan or campus-area networks.

We propose a new complex block floating-point format to reduce implementation complexity. The new format achieves wordlength reduction by sharing an exponent across the block of samples, and uses box encoding for the shared exponent to reduce ...

Measurement of Error Vector Magnitude (EVM) to Characterize the Impairment of the Tracking and Data Relay Satellite (TDRS) Channel [PDF]
A digital signal is transmitted via a carrier wave, it demodulates at a receiver, and locates at an ideal constellation point. However, noise distortion, carrier leakage, and phase noise can force a signal to divert from its ideal position to a new ...

All-Optical Generation of Two IEEE802.11n Signals for 2
A radio-over-fiber system capable of very spectrally efficient data transmission and based on multiple-input multiple-output (MIMO) and orthogonal frequency-division multiplexing (OFDM) is presented here.

Optimized Multiplicative Pre-Distortion PAPR Reduction Scheme for OTFS Signals
We present an iterative peak-to-average power ratio (PAPR) reduction scheme with multiplicative pre-distortion vectors for orthogonal time frequency space (OTFS) systems by making a compromise between the PAPR reduction and the bit error rate (BER ...

Performance of MB-OFDM UWB and WiMAX IEEE 802.16e converged radio-over-fiber in PON [PDF]
Experimental results about the performance of converged radio-over- fiber transmission including multiband- OFDM UWB and WiMAX 802.16e wireless over a passive optical network are reported in this paper. The experimental study indicates that UWB and WiMAX

Machine learning-based methods for piecewise digital predistortion in mmW 5G NR systems
Piecewise linearization techniques require dividing the signal into multiple pieces each linearized individually. Machine learning (ML) is one of the useful tools to perform the automatic division of these pieces.
