Electrical systems identification using Golay complementary series

Various techniques for interrogating systems are in current use, each having its own advantages and limitations. The author presents the design, implementation and testing of a PC and DSP based system that combines the well established properties of Golay complementary series with a cross-correlation technique, to perform electrical systems identification. Initially, the author develops the theoretical background and presents Golay codes adapted in a way to suit the application. Details of the design for the prototype model implemented in the work are given, and results of the tests carried out to evaluate the system´s performance are reported. It is shown that this new system is capable of working at very high speed and covering a wide frequency spectrum
