Packet Format Design and Decision Directed Tracking Methods for Filter Bank Multicarrier Systems

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
Packetized data transmission is commonly used in wireless communication systems. Each packet starts with a preamble which is used to synchronize the receiver with carrier frequency of the incoming signal, to find a good timing phase, and to identify the ...

Enhanced Carrier Phase Recovery Using Dual Pilot Tones in Faster-than-Nyquist Optical Transmission Systems

open access: yesPhotonics
Compared with high spectrum efficiency faster-than-Nyquist (FTN) backbone network, an enhanced carrier phase recovery based on dual pilot tones is more sensitive to capital cost in FTN metropolitan areas as well as inter-datacenter optical networks.

Reception of a Broadband Noise-Like Spread Spectrum Waveform Using a Rydberg Atom-Based Quantum RF Receiver

open access: yesIEEE Photonics Journal
We present experimental results demonstrating broadband reception of a noise-like spread-spectrum waveform using a Rydberg atom-based quantum radio frequency (RF) receiver. The transmitted waveform occupies a 20 MHz bandwidth around a 2.5 GHz carrier and
