Abstract

Traditional signal enhancement techniques, such as oversampling, face limitations due to their increased computational complexity and power consumption. As the demand for higher data rates and quality continues to grow, noise shaping techniques become crucial for improving the signal-to-noise ratio (SNR) without exacerbating these constraints. This paper establishes a co-simulation between Virtual Photonics Incorporated (VPI) and MATLAB to create a comprehensive Intensity Modulation Direct Detection (IM/DD) system using simulation tools. The study implements noise shaping techniques based on Finite Impulse Response (FIR) filters to mitigate the impact of quantization noise arising from low-bit Digital-to-Analog Converters (DACs) in the signal generation process, conducting system-level simulations to validate the reliability of the algorithm. In the MATLAB simulations, under Additive White Gaussian Noise (AWGN) channel conditions, the FIR-based noise shaping technique demonstrates a significant improvement in the Bit Error Rate (BER). The joint simulation with MATLAB and VPI shows that noise has been effectively shifted to higher frequency bands, achieving successful noise shaping.
