Application of Coded Modulation Technique to Multilevel Optical Transmission
نویسندگان
چکیده
Application of a spectrally efficient coded modulation technique called Trellis Coded Modulation (TCM) to optical Differential Quadrature Phase Shift Keying (oDQPSK) is discussed. Symbol Error Rate (SER) performance of the resultant system in the presence of Amplified Spontaneous Emission (ASE) noise is evaluated using the Karhunene Loeve Series Expansion (KLSE) method. Optical Signal to Noise Ratio (OSNR) penalty due to first order Polarization Mode Dispersion (PMD) effects of the proposed scheme is also evaluated.

Optical Multilevel Dpsk Systems with Coded Modulation
We propose and theoretically demonstrate the application of a specific coded modulation technique called as the Trellis Coded Modulation (TCM) to optical multilevel Differential Phase Shift Keying (DPSK) systems. In the process of identifying receiver structures for optical DPSK systems with coded modulation, it was discovered that though the parallel outputs from delay interferometer based opt...
متن کاملA Novel Method to Increase the Power Capacity of Transmission Lines Using Transformerless Static Synchronous Series Compensator
In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...

In this paper, we investigate spectrally efficient coded multilevel modulation for direct-detection optical fiber communication systems with optical amplifiers. The dominant noise in the received photocurrent is the beat noise of amplified spontaneous emission with signal and itself. Although the decision variables are higher-order Chi-square distributed, we approximate them by first-order Chi-...

In this paper, a 7-level Diode Clamped Multilevel Inverter (DCMLI) is simulated with three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Dispos...
متن کاملPolarization-multiplexed rate-adaptive non-binary-quasi-cyclic-LDPC-coded multilevel modulation with coherent detection for optical transport networks.
In order to achieve high-speed transmission over optical transport networks (OTNs) and maximize its throughput, we propose using a rate-adaptive polarization-multiplexed coded multilevel modulation with coherent detection based on component non-binary quasi-cyclic (QC) LDPC codes. Compared to prior-art bit-interleaved LDPC-coded modulation (BI-LDPC-CM) scheme, the proposed non-binary LDPC-coded...
