very recently, laywine and mullen extended the table ( l-m table ) . in this article we will give some construction methods of mutually orthogonal frequency squares . as an application we improve the lower bounds for almost half of the entries in l-m table and conclude a new table 2001年,laywine和mullen將此表擴(kuò)充為l-m表,本文給出正交頻率方的一些組合構(gòu)造方法,同時(shí)改進(jìn)了l-m表中近一半下界值,并形成新的下界表。
