- ItemMicrowave data transmission by means of an optimal bandwidth multichannel QPSK system(Stellenbosch : Stellenbosch University, 2004) Malan, Jacques de Villiers; De Swardt, J. B.; Stellenbosch University. Faculty of Engineering. Dept. of Electrical and Electronic Engineering.ENGLISH ABSTRACT: The increase in the complexity and functionality of new satellites leads to a growing demand for a digital communication system operating at a much higher bit rate than before. The main purpose of this thesis is to address precisely this problem. The theory as well as a practical high speed system are custom-developed. The goal of this thesis is not to reinvent the wheel, but to use off-the-shelf products as far as possible. This system demonstrates that a very high data rate is not out of reach for a developer with limited funds. The secondary goal is to understand the operation of this communication system. The emphasis is on the inaccuracies in the system. A design tool is created to act as a vehicle for understanding the influence of a single variable on the performance of the entire system.
