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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
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, ...
