ABSTRACT:
A method of separating mixed wireless signals is provided. The method includes receiving, at an antenna comprising a first quantity of antenna elements, mixed signals comprising a mixture of source signals communicated from a second quantity of wireless signal sources, and separating the mixed signals to estimate the source signals. The second quantity is greater than the first quantity, and the source signals communicated from at least one of the wireless signal sources are received at the antenna as complex signals.
