Multiple Access Acquisition Technique Based on CAZAC Sequences in OFDM System

Abstract:

Article Preview

The sliding correlation acquisition technique, which is based on CAZAC sequences in OFDM time-domain multiple access, is proposed and verified. This technique takes advantage of the characteristics of good auto-correlation and cross-correlation characteristics of CAZAC sequences in time domain and achieves the purpose of multiple access discrimination by the different correlation peaks. Whats more, this technique can increase acquisition performance by multiple frames adding up in a receiver according to the receivers demand. The simulation in AWGN channel shows that the technique is feasible and effective in time-domain signal acquisition in OFDM system.
