Portable Signals Analysis Solutions Using Signalworks(trademark) : A Process Guide For Analysts And Students

摘要

Signalworks(trademark) is a signals analysis software suite designed to be installed on Windows and Linux portable computing platforms. The demodulation applications within the program offer considerable processing capability for a variety of signals coupled with a graphical interface that is both easy to use and configure. This thesis examines the process of building test signals within Signalworks and then processing them with the available demodulation applications to define important parameters used to identify and analyze signals. Although Signalworks version 4.0 is unable to demodulate Orthogonal Frequency Division Multiplexed (OFDM) signals often used in wireless communications, it can process Binary Phase-Shift Keyed (BPSK) and Quadrature Phase-Shift Keyed (QPSK) signals used in the 802.11b standard. While future versions may include OFDM demodulation capability, this analysis includes the feasibility of using Signalworks in a lab environment to demonstrate and educate students on signal characteristics including wireless communication signals.
