Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

Overview of existing and emerging wireless communications systems; interference, blocking, and spectral efficiency; radio propagation and fading models; performance of digital modulation in the ...

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing ...

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 ...

1. Basic Information and Coding Theorems: entropy, Huffman Codes, Mutual Information, Channel Capacity, Shannon’s theorems; 2. Error Control Coding: Coding ...

A common trend in wireless device integration, specifically transceivers, is to incorporate the analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) into a single IC or module.

Until the last few years, the narrow bandwidth (300kHz) of the 950MHz radio channels, which was adequate for the audio and technical standards of the all-analog world, was insufficient to handle the ...

In this proposed paper, a simulation of convolutional encoder and Viterbi decoder presented. This paper focuses on the performance study of Viterbi algorithm by varying parameters like constraint ...
