A PCM-Based Vocoder/Decoder, a voice codec software based on PCM of voice signals to send over data network, whose quantizer provides both mid-rise and mid-tread quantization techniques, and an ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...

#PCM import numpy as np import matplotlib.pyplot as plt # Parameters sampling_rate = 5000 # Sampling rate (samples per second) frequency = 50 # Frequency of the message signal (analog signal) duration ...

The amount of information the humble seven-segment display can convey is surprising. There are the ten numerals, dead-ringers or reasonable approximations for about half the alphabet, and even a few ...

Abstract: For next-generation green communication systems, this article proposes an innovative communication system based on frequency-diverse array-multiple-input multiple-output (FDA-MIMO) ...

Abstract: This paper introduces a novel reconfigurable intelligent surface (RIS)-aided wireless communication scheme, termed RIS code index modulation with quadrature ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
