Abstract: To address the performance bottlenecks of convolutional coding and π/4-DQPSK modulation in satellite communications, this paper proposes an optimized scheme employing Turbo codes combined ...

Abstract: Multi-input frequency shift keyying can overcome the problem of low band utilization rate in the process of binary frequency shift keyying, and has a wide practical application range. In ...

The deployment of low earth orbits is seen as a promising way of enlarging data capacities as well as high data rates. Catering to these interests, optical communication presents possible ways of ...

Different types of modulation techniques are used in telecommunication for transmitting and receiving radio frequency (RF) signals. With MATLAB tools we can analyse the modulation techniques used for ...

Download this article in PDF format. We also want to recognize Rick Gentile of MathWorks as a co-author of this article. Modulation identification is an important function for an intelligent receiver.

The Global Navigation Satellite Systems (GNSS) data signals contains the ephemeris information of each satellite, which is then used by a receiver to obtain its ...
