Description
Summary:To solve the problem that the number of sequences in the complete complementary sequence set is limited, periodic quasi-complementary sequence set was constructed.Firstly, based on the circular Florentine array, the near optimal periodic quasi-complementary sequence set was constructed by using the mapping function on <inline-formula><!--math xmlns="http://www.w3.org/1998/Math/MathML"> <msub> <mi>&#x2124;</mi> <mi>N</mi> </msub> </math--></inline-formula> .The obtained periodic quasi-complementary sequence sets had new subsequence lengths.Secondly, based on the one-coincidence frequency-hopping sequence set, the asymptotically optimal periodic quasi-complementary sequence set was constructed by defining the mapping function from <inline-formula><!--math xmlns="http://www.w3.org/1998/Math/MathML"> <msub> <mi>&#x2124;</mi> <mi>q</mi> </msub> </math--></inline-formula> to <inline-formula><!--math xmlns="http://www.w3.org/1998/Math/MathML"> <msub> <mi>&#x2124;</mi> <mrow> <mi>q</mi><mo stretchy='false'>(</mo><mi>q</mi><mo>&#x2212;</mo><mn>1</mn><mo stretchy='false'>)</mo></mrow> </msub> </math--></inline-formula>.The comparison results show that compared with the existing periodic quasi-complementary sequence sets, the proposed method contains more sequences with the same subsequence length, and can support more users in multi-carrier communication system.
