Abstract:

A new periodic correlation discrete signal is proposed, which can be referred as perfect almost-quadriphase sequence pairs. The transformation properties and existing condition of the perfect almost-quadriphase sequence pairs were presented. Using these properties and condition the searching range of the perfect almost-quadriphase sequence pairs can significantly reduced, and computing efficiency can be greatly improved. The construction method of perfect almost-quadriphase sequence pairs based on BTP transform is proposed. Using the method the perfect almost-quadriphase sequence pairs can be constructed directly from perfect almostbinary sequence pairs searched by computer. The new perfect signal enriches the theory of sequence pairs and perfect discrete correlated signals.

Key words: information processing technology, perfect signal, correlation, almost-quadriphase signal, sequence pairs
