Real-time Nyquist pulse generation beyond 100 Gbit/s and its relation to OFDM.

چکیده
Nyquist sinc-pulse shaping provides spectral efficiencies close to the theoretical limit. In this paper we discuss the analogy to optical orthogonal frequency division multiplexing and compare both techniques with respect to spectral efficiency and peak to average power ratio. We then show that using appropriate algorithms, Nyquist pulse shaped modulation formats can be encoded on a single wavelength at speeds beyond 100 Gbit/s in real-time. Finally we discuss the proper reception of Nyquist pulses.

Timing, carrier frequency and phase recovery for OFDM and Nyquist signals using a mean modulus algorithm.
Efficient algorithms for timing, carrier frequency and phase recovery of Nyquist and OFDM signals are introduced and experimentally verified. The algorithms exploit the statistical properties of the received signals to efficiently derive the optimum sampling time, the carrier frequency offset, and the carrier phase. Among the proposed methods, the mean modulus algorithm (MMA) shows a very robus...

We have demonstrated the generation of a 320 Gb/s NyquistOTDM signal by rectangular filtering on an RZ-OTDM signal with the filter bandwidth (320 GHz) equal to the baud rate (320 Gbaud) and the reception of such a Nyquist-OTDM signal using polarization-insensitive time-domain optical Fourier transformation (TD-OFT) followed by passive filtering. After the time-to-frequency mapping in the TD-OFT...
متن کاملSoft-FEC Implementation for High-Speed Coherent Optical OFDM Systems
Nowadays one of the discussed solutions for optical transmission systems at 100 Gbit/s (N x 100 Gbit/s) and beyond is coherent optical orthogonal frequency division multiplexing (CO-OFDM). Commonly hard-decision forward error correction (FEC) with the redundancy of 7% is assumed. Recently the improvement of the receiver sensitivity was analyzed by using a low density parity check (LDPC) code th...

In this work, the approach of the distributed transversal filter for Optical CDMA systems is addressed. It demonstrates that pulse generation and correlation functions can be accomplished in the electrical domain for multi-Gbit/s systems. The practicalities of the approach were assessed using a state of the art GaAs MMIC process. A innovate transversal filter, which is termed the dual drain-lin...
