摘要:Sequences with good properties such as optimal correlation, low PAPR and large family size are desirable in modern wireless communication and radar. 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 via algebraic and number theory. We shall also introduce a new family of sequences with large size, optimal correlation and low PAPR that outperforms the known ones used in 5G.
