Abstract :
We consider a general n × n MIMO system excited by unobservable inputs that are spatially independent, cyclostationary with unknown statistics. We provide a set of conditions under which the system is uniquely identifiable based on second-order frequency-domain correlations of the system output. Such a MIMO problem appears in many applications, such as multi-user communications and separation of competing speakers.
