“…us, this effect needs to be treated for higher transmission speeds. In our proposed model, we compensate the OFCD by using digital filters in the time domain, due to its several advantages over the frequency domain implementation [25] for improved selection of data signals. With the help of these procedures, the proposed framework performs better in terms of BER, OSNR, and Q-factor.…”

Fiber optic communication systems (FOCSs) have attained a lot of attention by revolutionizing the telecommunication industry and offering new possibilities with the technical advancements in state-of-the-art high speed digital electronics. Advanced modulation formats make use of the phase, amplitude, and polarization of the optical signals at the same time to provide high spectral efficiency as compared with 1 bit/s/Hz for the intensity modulation direct detection system (IMDD), but are highly prone to transmission impairments. Thus, the effects that add up to the optical fiber impairments such as optical fiber chromatic dispersion (OFCD), polarization model dispersion (PMD), and phase offset and noise (POaN) need to be addressed at the receiver side. The development of components and algorithms to minimize these effects in next generation FOCSs with 100 Gbps data rate and beyond with long-haul transmission is still a challenging issue. In this paper, digital signal processing- (DSP-) assisted dispersion and nonlinear compensation techniques are presented to compensate for physical layer impairments including OFCD, PMD, and POaN. The simulations are performed considering Dual Polarization- (DP-) QPSK modulation format to achieve two-fold data rate to achieve spectral efficiency of 3.28 bits/s/Hz by making use of the polarization diversity and system performance is investigated in terms of bit error rate (BER), constellation diagrams, and quality factor (Q-factor) for different values of optical signal-to-noise ratio (OSNR), launch power (PL), and fiber length.

High capacity long haul communication and cost-effective solutions for low loss transmission are the major advantages of optical fibers, which makes them a promising solution to be used for backhaul network transportation. A distortion-tolerant 100 Gbps framework that consists of long haul and high capacity transport based wavelength division multiplexed (WDM) system is investigated in this paper, with an analysis on different design parameters to mitigate the amplified spontaneous emission (ASE) noise and nonlinear effects due to the fiber transmission. The performance degradation in the presence of non-linear effects is evaluated and a digital signal processing (DSP) assisted receiver is proposed in order to achieve bit error rate (BER) of 1.56 × 10−6 and quality factor (Q-factor) of 5, using 25 and 50 GHz channel spacing with 90 μm2 effective area of the optical fiber. Analytical calculations of the proposed WDM system are presented and the simulation results verify the effectiveness of the proposed approach in order to mitigate non-linear effects for up to 300 km length of optical fiber transmission.

“…Bit-Interleaved Coded Modulation Iterative Detection (BICM-ID), which is one of the coded modulations, offers remarkable improvements of BER performance by iteratively exchanging bitwise soft information between a demodulator and a decoder [3]. A few optical transmission experiments have been recently reported using multi-dimensional modulation with the BICM-ID [4,5].…”

We numerically evaluate Bit Error Rate (BER) performance of four-and eight-dimensional modulation formats with Bit-Interleaved Coded Modulation Iterative Detection (BICM-ID) compared with Gray mapped and natural binary mapped two-dimensional formats for high-speed optical communication systems. The BICM-ID, which is composed of a demodulator and a decoder, effectively improves power efficiency of the multidimensional formats taking into account receiver sensitivity and transmission capacity per symbol. Further, we quantitatively verify that the BER performances significantly depend on a priori/extrinsic mutual information exchange between a demodulator and a decoder, which is illustrated by Extrinsic Information Transfer (EXIT) chart.
