In this paper, we propose three different user selection methods for an OFDM based downlink closed loop multi-user MIMO cellular system.
All-optical slotted networks rely on fast wavelength tunable lasers to achieve any-to-any communication over the same physical medium (the optical fiber).
We experimentally investigate the sensitivity of different 43 Gb/s formats to non-white noise which occurs in a reconfigurable network, and discuss the system design to reduce its penalty.
In Multiple Input Multiple Output (MIMO) system, the transmitter obtains channel state information (CSI) by channel estimation.
We highlight the importance of the laser source phase noise in sensing applications and show that the standard Lorentzian linewidth criterion is not sufficient to characterize the performance of a
The performance of coded modulation schemes based on the concatenation of a forward-error correction (FEC) code and differentially encoded quadrature amplitude modulations (QAMs) in the presence of
Coherent detection with digital signal processing (DSP) significantly changes the ways impairments are managed in optical communication systems.
The tolerance to PMD of 100 Gb/s PDM-QPSK systems is investigated in linear and nonlinear regime.
We investigate the impact of the opto-electronic front-end frequency response on Kramers-Kronig (KK) receivers.
We discuss the influence of optical and electrical filtering on the performance of beat-noise limited direct detection of differential phase shift keying (DPSK).
