Claim Text:
1. A transmission signal generating and detecting method using code sequences, characterized in that the method comprises: generating a multiplexing-spread chip sequence with a multiplicity being equal to or larger than “1”, the multiplicity being equal to the code length of a coupling-purpose code sequence, by multiplexing a spread chip sequence formed in a way that multiplies a spreading-purpose code sequence, a chip of the coupling-purpose code sequence, the coupling-purpose code sequence being a code sequence for linearly coupling a plurality of code pulse trains for spreading, and a chip of a localizing-purpose code sequence, the localizing-purpose code sequence being a code sequence for determining the shift time of the spreading-purpose code sequence, together with respect to the chips of the coupling-purpose code sequence, generating transmission signals on the basis of transform signals generated by transforming at least a single multiplexing-spread chip sequence or a plurality of multiplexing-spread chip sequences and transmitting the generated transmission signals; and acquiring the multiplexing-spread chip sequence in a time domain or a frequency domain from the transform signals by detecting the transmission signals, multiplying the acquired multiplexing-spread chip sequence by the spreading-purpose code sequence, and detecting a localization pulse of the coupling-purpose code sequence and/or a localization pulse of the localizing-purpose code sequence from the multiplied signals.
