Field Trial of a Flexible Real-Time Software-Defined GPU-Based Optical Receiver

چکیده
We introduce a flexible, software-defined real-time multi-modulation format receiver implemented on an off-the-shelf general-purpose graphics processing unit (GPU). The flexible is able to process 2 GBaud 2-, 4-, 8-, and 16-ary pulse-amplitude modulation (PAM) signals as well 1 16- 64-ary quadrature amplitude (QAM) signals, with the latter detected using Kramers-Kronig (KK) coherent receiver. Experimental performance evaluation shown for back-to-back. In addition, by JGN high speed R&D network testbed, evaluated after transmission over 91 km field-deployed optical fiber reconfigurable add-drop multiplexers (ROADMs).

متن کاملA Real-Time Capable Software-Defined Receiver Using GPU for Adaptive Anti-Jam GPS Sensors
Due to their weak received signal power, Global Positioning System (GPS) signals are vulnerable to radio frequency interference. Adaptive beam and null steering of the gain pattern of a GPS antenna array can significantly increase the resistance of GPS sensors to signal interference and jamming. Since adaptive array processing requires intensive computational power, beamsteering GPS receivers w...
متن کاملA Real-Time PC-Based Software Radio DVB-T Receiver
We propose a PC-based real-time software Digital Video Broadcasting-Terrestrial (DVB-T) receiver, including hardware, driver, and software parts. The total data rate of DVB-T is much greater than that of Digital Audio Broadcasting (DAB). A more efficient signal processing algorithm than our previous software DAB receiver is necessary to improve the speed of the software part of the DVB-T receiv...
متن کاملA Flexible Real-Time Software Synthesis System
Aura is a new sound synthesis system designed for portability and flexibility. Aura is designed to be used with W, a real-time object system. W provides asynchronous, priority-based scheduling, supporting a mix of control, signal, and user interface processing. Important features of Aura are its design for efficient synthesis, dynamic instantiation, and synthesis reconfiguration. operating syst...
متن کاملA Custom Approach for a Flexible, Real-Time and Reliable Software Defined Utility
Information and communication technologies (ICTs) have enabled the evolution of traditional electric power distribution networks towards a new paradigm referred to as the smart grid. However, the different elements that compose the ICT plane of a smart grid are usually conceived as isolated systems that typically result in rigid hardware architectures, which are hard to interoperate, manage and...
