摘要: A code converting apparatus is designed to estimate the incoming time and like of a signal modulated by spreading sequence composed m elements in set having n kinds symbols as accurately. symbol memory section 102 stores converted obtained concatenating consecutive 2d at center each pattern pi 4d A. The structured so that d immediately preceding following are identical corresponding pattern. specifying 103 specifies matching for every assigning coding cycle sequence. generating 104 adds portion which assigned signal. 105 concatenates added pattern, an order equivalent concatenated symbols.
