Enhanced Signal-To-Noise Ratio (SNR) Digital Cascaded Pulse-Code Modulation Radio Using Fiber

Abstract

This paper presents the design and implementation of an advanced Signal-to-Noise Ratio (SNR) digital cascaded Pulse-Code Modulation (PCM) radio system, leveraging fiber optic communication for superior signal quality. The proposed system integrates cutting-edge technologies in digital signal processing, fiber optics, and modulation schemes to achieve enhanced performance in terms of data fidelity and robustness against noise. The Pulse-Code Modulation technique is employed with a high-resolution encoding scheme to accurately represent analog signals. Advanced Digital Signal Processing (DSP) algorithms are incorporated to further refine the signal during both the encoding and decoding stages, employing adaptive filtering and noise reduction methods. The transmission medium is facilitated by fiber optic cables, chosen for their high bandwidth and immunity to electromagnetic interference. The optical communication is enhanced through sophisticated modulation techniques, such as Quadrature Amplitude Modulation (QAM), to maximize data transmission rates.
