As data centers evolve to sustain the economic scale in network traffic, optical interconnections are adapted to support the vast amount of capacity requirements. Among emerging solutions is the incorporation of digital-signal-processing (DSP) functionalities at the receiver to compensate for the optical fiber and optoelectronic components impairments. The bottleneck in such architecture is often implementing a high-resolution and high-speed analog-to-digital-converter (ADC) device, which usually leads to massive power consumption and high costs. In this paper, we propose novel transmission schemes based on low-resolution ADCs, termed DSP-enhanced analog-todigital conversion. The proposed methods are based on the mathematical principle of predictive quantization, combined with linear equalization theory. Mathematical analysis and performance bounds associated with common channel impairments are derived. Simulation results demonstrate that the DSP-enhanced ADC provides a significant signal-to-noise-ratio (SNR) gain and, subsequently, may enable heavy digital compensation with reduced-resolution ADCs.Index Terms: Fiber-optic communications analog-to-digital conversion (ADC), quantization, bit error rate (BER), differential pulse code modulation, inter-symbol interference (ISI), linear equalization.

“…Minimum shift keying is a continuous phase frequency shift keying .FSK is the digital equivalent of frequency modulation with modulation index h=0.5.MSK is termed as minimum shift keying. The minimum shift keying has used two frequencies which are scattered by 1/2T and phase disruption is avoided in symbol boundaries 8 . The MSK transmission is a variant of Offset-QPSK technique.…”

Gaussian minimum shift keying is a spectrum efficient modulation scheme. The GMSK is better than normal MSK. For avoiding the interference between adjacent signals have to use GMSK modulation scheme.The coherent receiver implementing is easy. But the non-coherent receiver implementing is a complex. The non-coherent receiver produces a complex interference effects in a multipath channel. In this paper we present some analysis and performance between coherent and non-coherent receiver for GMSK and DQPSK and shows the simulation results.

“…This assumption is only valid for multicarrier systems with large number of carriers and is, in general, not applicable to single carrier systems. In [7], [8], bit error rate expressions are derived assuming the ADC QN is uniformly distributed for M -ary pulse amplitude modulation (MPAM) and quadrature phase-shift keying (QPSK) modulation techniques. However, the analysis is specific to coherent detection of MPAM and QPSK detection and is not applicable for non-coherent OOK detection.…”

This paper investigates the word length requirement of an analog-to-digital (ADC) converter for coherent and noncoherent detection of On-Off Keying (OOK) schemes. The paper presents closed-form expressions for coherent and non-coherent detection in terms of bit error rate in the presence of quantization noise (QN) and additive white Gaussian noise (AWGN) channels. The analytical models show that for coherent as well as noncoherent demodulation of OOK schemes in AWGN channels and affected by QN, a 4-bit ADC is able to provide close to optimum performance. As OOK is popularly being employed in event-driven radios, we extend our analysis to these radios. Our analysis shows that for event-driven radios (also referred to as wakeup radios) a 4-bit ADC is able to provide close to optimum performance. Furthermore, in the paper all the analytical models are in close agreement with the simulation results.
