Abstract
A novel precoding-based initial ranging signal is presented for the successive multiuser detection and interference cancellation (SMUD) algorithm in OFDMA uplink systems. The ranging codes in the multiple ranging symbols are coded by the precoding matrix. The performance of the SMUD algorithm is greatly improved by using the decoded signal of the received precoded ranging signal.
