This repository contains a MATLAB simulation of Fast Orthogonal Frequency Division Multiplexing with Index Modulation (Fast-OFDM-IM), a next-generation waveform combining Fast-OFDM and subcarrier ...

MATLAB PCM System Simulator demonstrating digital signal processing fundamentals. Features sampling, quantization (uniform/μ-law), multiple encoding schemes, and signal reconstruction. Includes ...

Abstract: This paper contains the study of modulation identification for both analog and digital signals using convolution neural network. Modulation classification involves identifying the modulation ...

Abstract: This paper focuses on the design and implementation of an Earth station transceiver system that employs an innovative approach combining subcarrier composite Pulse Code Modulation (PCM), ...

ABSTRACT: This study introduces a Hybrid Bimodal Model for Analog-to-Digital (ADC) and Digital-to-Analog (DAC) signal conversions, addressing limitations of traditional systems, such as inefficiencies ...

The process of varying the AMPLITUDE of a sound, often periodically. An example of AM is the violinist's TREMOLO, where the amplitude of the vibrating string is rapidly altered by a movement of the ...
