Peak-to-average power ratio reduction using coded signal in optical-orthogonal frequency division multiplexing systems

Abstract

A new coding scheme is proposed using a variable rate for an all-optical sampling orthogonal frequency-division multiplexing system, to minimise the peak-to-average power ratio. Cyclic rotation and code rate variation are shown to improve the peak envelope power. The proposed idea comprises of searching for a variable code rate selection for the binary input data and cyclic rotation, followed by codeword inversion.

Effect of Raman Amplifier and Cyclic Prefix on O-OFDM System Using Phase Modulation

“…Global parameters of OFDM transmitter and receiver are shown in Table 1. Two 7-pole lowpass Bessel filters centered at the carrier frequency, 30 GHz in this example are used [13]. …”

“…With the insertion of OADM data rates greater than 100 Gb/s can also be achieved. A new coding scheme, using a variable rate for all optical OFDM systems is proposed for reduction of peak to average power ratio (PAPR) [12][13][14][15][16][17].…”

Impact of Initial Laser Phase Values on Soliton Transmission

“…When spatial optical solitons have phase singularities, they explain the internal structure of the beam and can be stabilized by the light self-action generating nonlinear self-trapped optical beams carrying phase dislocations [11]. We achieved our results with the help of Simulative analysis of integrated DWDM and MIMO-OFDM system with OADM was done recently for optical-OFDM system and Monitoring and Compensation of Optical Telecommunication Channels [12][13][14][15][16][17].…”

Performance Analysis of 16 Channel WDM System with 4 OADM

“…To increase the optical signal-to-noise ratio (OSNR) for increasing the transmission distance [15]. We have already achieved good results within MIMO-OFDM system with OADM recently for optical-OFDM system and monitoring and compensation of optical telecommunication channels [16][17][18][19][20][21].…”
