ABSTRACT:
Disclosed is an apparatus for creating an aperiodic recursive multiplex (ARM) code having a predetermined length by receiving a first sequence having a given length. The apparatus outputs a third sequence by multiplying the first sequence by a second sequence alternating between +1 and −1, the second sequence being identical in length to the first sequence. A fourth sequence is output by time-multiplexing the first sequence and the third sequence.
