报告摘要:
Large sets of sequences with optimal correlation and low PAPR are desirable in modern wireless communication including 6G and Wifi 8. In this talk, we shall introduce the metrics (including correlation and PAPR) of sequences for measuring their performance in practical applications. We then recall the well-known bounds on these metrics, and some classical sequences meeting the bounds. We shall also introduce a new family of sequences with large size, optimal correlation and low PAPR. The numerical results show that the proposed sequences outperform the known sequences used in the standard of 5G.
