Abstract
In this letter, the realizable direct-sequence code-division multiple-access (DS-CDMA) system occupying Nyquist bandwidth is developed. Several frequently-adopted spreading codes are examined for realization feasibility in the bandlimited DS-CDMA system. It is shown that Nyquist chip-rate transmission can be practically achieved for the bandlimited DS-CDMA system using frequently-adopted spreading codes at the sacrifice of very little user capacity.
