A Novel Compact Preamble Structure for Timing Synchronization in MIMO- OFDM Systems Using CAZAC Sequences
نویسندگان
چکیده
To increase the throughput of transmission systems, MIMO-OFDM technology allows for a better reach and rate of transmission and improves the reception. The synchronization between the transmitter and the receiver has become a big challenge. A bad timing synchronization causes the loss of a lot of information in a MIMO-OFDM system. In this paper, we propose a novel compact preamble structure based on orthogonal CAZAC sequences. Simulations results show that the proposed solution presents a good performance at a low SNR in AWGN and multipath fading Rayleigh channels. KeywordsMIMO-OFDM system; Timing synchronization; CAZAC sequences; Compact preamble.
