This tutorial paper gives an overview of the implementation aspects related to turbo
decoders, where the term turbo generally refers to iterative decoders intended for parallel …

In this paper, we optimize the constellation sets to be used in communication systems
affected by phase noise. The main objective is to find the constellation which maximizes the …

A digital communication system, having a transmitter to transmit a digital signal; and a
receiver to receive the digital signal; wherein the digital signal utilizes a 32APSK system with …

For decades, the de facto standard for forward error correction was a convolutional code
decoded with the Viterbi algorithm, often concatenated with another code (eg, a Reed …

The pragmatic approach to coded continuous-phase modulation (CPM) is proposed as a
capacity-achieving low-complexity alternative to the serially concatenated CPM (SC-CPM) …

In recent years, the number of Earth Observation missions has been exponentially
increasing. Satellites dedicated to these missions usually embark with payloads that …

Future space missions will put severe constraints on communication links in terms of data
rates, bandwidth occupancy, complexity, and performance. The requirements imposed by …

This paper investigates the design of power and spectrally efficient coded modulations
based on amplitude phase shift keying (APSK) with application to broadband satellite …

Satellite communications are a well-established research area in which the main innovation
of last decade has been the use of multi-carrier modulations and more robust channel …

Satellite modems are critical components in satellite communication networks. Especially,
they determine the entire communication regime in traditional systems where the satellites …
