Abstract:

A variety of binary sequences exhibit known correlation properties which can be exploited to simultaneously measure system functions in a multiple-input, multiple-output system. This work considers the practical application of codes such as linear maximal sequences and Gold codes for these measurements, and experimental data are presented for a fluid--structure interaction problem. Applications in multichannel active noise control systems and to the measurement of mutual coupling factors in transducer arrays are discussed.
