Characterization Of The Rfx400 For Use In Software Defined Radio, Edward Adams
Characterization Of The Rfx400 For Use In Software Defined Radio, Edward Adams
Computer Engineering
While software defined radio is an extremely flexible technology that is fairly rarely used, as a single purpose radio is much cheaper, it provides an excellent means of learning RF and communications skills through the lens of digital electronics, and it would behoove a Cal Poly student interested in these areas to take on a project in software defined radio. This project aims to lower the barrier to entry for future students to undertake such a project. The use of an up-converter/down-converter is documented for future students to interface with.
Ofdm Simulation In Matlab, Paul Guanming Lin
Ofdm Simulation In Matlab, Paul Guanming Lin
Electrical Engineering
The objective of this project is to demonstrate the concept and feasibility of an OFDM system, and investigate how its performance is changed by varying some of its major parameters. This objective is met by developing a MATLAB program to simulate a basic OFDM system. From the process of this development, the mechanism of an OFDM system can be studied; and with a completed MATLAB program, the characteristics of an OFDM system can be explored.

Touch Screen Sound Controller, James Fenley, Jonathan Law
Electrical Engineering
The Touch Screen Sound Controller sets out to explore the use of a touch screen as a sound control interface for the disk jockey profession. In addition, the project aims to provide an alternate means of transferring audio data by way of TCP/IP communications as opposed to MIDI. By applying our method, a user may stream pulse-code modulated data from a server onto a client’s RAM via an Ethernet connection. A 32bit, 200MHz ARM9 microprocessor addresses data from the RAM and proceeds with executing DSP instructions from the user. The connection between the touch screen and the central microprocessor is …
