Demonstration of Tunable and Reconfigurable Optical Nyquist Channel Aggregation of QPSK-to-16QAM and BPSK-to-4PAM Using Nonlinear Wave Mixing and a Kerr Frequency Comb
Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Yiming Cao, Fatemeh Alishahi, Ahmad Fallahpour
A tunable and reconfigurable optical Nyquist channels aggregation is experimentally demonstrated. The proposed method two aggregate lower order modulation formats into a single higher order one. Two 16 Gbaud QPSK Nyquist pulses aggregated to a 16 QAM Nyqui ...
IEEE2019Effects of erbium-doped fiber amplifier induced pump noise on soliton Kerr frequency combs for 64-quadrature amplitude modulation transmission
Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Fatemeh Alishahi, Lin Zhang, Ahmad Fallahpour, Amirhossein Mohajerin Ariaei
We experimentally investigate the effects of erbium-doped fiber amplifier induced pump noise on soliton Kerr frequency combs for 64-quadrature amplitude modulation (QAM) transmission. We find that the optical carrier-to-noise ratios (OCNRs) of the comb lin ...
2018Optimal Number of Paths with Multipath Routing in Hybrid Networks
Patrick Thiran, Sébastien Christophe Henri
In recent years, multipath routing, i.e., employing several paths simultaneously, has emerged as an efficient way to provide significant throughput gains in local networks. This has been observed both with technologies that are not subject to interference, ...

IEEE2018Experimental Investigation of the Effect of EDFA-Generated ASE Noise added to the Pump of a Kerr Frequency Comb
Tobias Kippenberg, Arne Kordts, Fatemeh Alishahi, Lin Zhang, Ahmad Fallahpour
We experimentally investigate the effect of EDFA-induced pump ASE noise on cavity-soliton Kerr combs for 64-QAM transmission. We find that all comb optical carrier-to-noise ratios (OCNRs) are similar with a fixed pump OCNR and comb linewidths almost remain ...
Ieee2017Method to optimize the communication parameters between an access point and at least one client device
Patrick Thiran, Julien Pierre Sacha Herzen, Ruben Merz
A method to optimize the communication on a channel between an access point and at least one client device, said channel being characterized by a center frequency and a bandwidth, comprises: establishing a connection on a first channel according to a first ...
2014Maximum Throughput Gain of Compute-and-Forward for Multiple Unicast
Michael Christoph Gastpar, Jasper Goseling
Compute-and-Forward (CF), also known as reliable physical layer network coding, is a technique that provides the possibility of exploiting the features of broadcast and superposition in wireless networks. It has been shown that the throughput for multiple ...
Institute of Electrical and Electronics Engineers2014A Parallelized Layered QC-LDPC Decoder for IEEE 802.11ad
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Alessandro Cevrero, Nicholas Alexander Preyss
We present a doubly parallelized layered quasi-cyclic low density parity-check decoder for the emerging IEEE 802.11ad multigigabit wireless standard. The decoding algorithm is equivalent to a nonparallelized layered decoder and, thus, retains its favorable ...
IEEE2013Block-Floating-Point Enhanced MMSE Filter Matrix Computation for MIMO-OFDM Communication Systems
Andreas Peter Burg, Carl Christian Sten Dominic Senning
n this paper we present an architecture for an MMSE filter matrix computation unit for signal detection in MIMO-OFDM communication systems. We propose to compute the required matrix inverse based on a Cholesky decomposition, followed by a Gauss-Jordan matri ...
2013A 2.78 mm2 65 nm CMOS Gigabit MIMO Iterative Detection and Decoding Receiver
Iterative detection and decoding (IDD), combined with spatial-multiplexing multiple-input multiple-output (MIMO) transmission, is a key technique to improve spectral efficiency in wireless communications. In this paper we present the—to the best of our know ...
