Experimental study on the performance of reduced rank timing acquisition scheme for multiple access communications

This work studies the performance of a data-driven reduced rank scheme for rapid timing acquisition in multiple access communications. Our results show that when only a limited amount of preamble bits are available, instead of the true second-order statistics (SOS), the reduced rank scheme provides reliable timing information. Exploiting the structure of the multiple access interference, the data driven reduced-rank timing acquisition scheme demonstrates almost near-far resistant performance in signal acquisition.
