<p>A receiving method for receiving, at a receiving end, signals having a known period N by use of a matched filter used for signals of N chips acquired by the steps of (1) DFT converting the signals having the period N to acquire an N-th-order matrix (c<SUB>0</SUB>, c<SUB>1</SUB>,...c<SUB>N - 1</SUB>)<SUP>t</SUP>; (2) DFT converting signals of N arbitrary chips to acquire an N-th-order matrix (d<SUB>0</SUB>, d<SUB>1</SUB>,...d<SUB>N - 1</SUB>)<SUP>t</SUP>; (3) acquiring an N-th-order matrix (c<SUB>0</SUB>/d<SUB>0</SUB>, c<SUB>1</SUB>/d<SUB>1</SUB>,...c<SUB>N - 1</SUB>/d<SUB>N - 1</SUB>)<SUP>t</SUP> from the two matrixes acquired by the steps of (1) and (2); (4) reverse-DFT converting the N-th-order matrix, which is acquired by the step of (3), to acquire an N-th-order matrix (e<SUB>0</SUB>, e<SUB>1</SUB>,...e<SUB>N - 1</SUB>)<SUP>t</SUP>; and (5) maximizing e<SUB>0</SUB> to acquire the signals of the N chips for which at least e<SUB>1</SUB> is zero.</p> |
