Abstract (in Japanese) (See Japanese page) 
(in English) Even when we communicate with spread spectrum, we have take into account occupide frequency bandwith.
It have been studied to the spread spectrum signal with narrow band.
However, there are papers in which randum code is used as the spread spectrum code.
Thus, we need to study on realistic spread spectrum codes.
Therefore, in this study, a preffered pare of M-sequence is applied to the spread spectrum codes
for nallow band DS-CDMA translation.
As the result, computer simulation shows that
the BER performance is just 1dB degraded from that of ideal matched filter reception without bandlimitation.
