Performance of Direct sequence spread spectrum code division multiple Access (DSSS – CDMA) under the presence of multiple users is addressed in this Engineering report. A system model for DSSS – CDMA, Quasi-orthogonal spreading code is developed. This Engineering report shows that as more access the system simultaneously, the noise level and hence the error rate increases, only gradual does the system degrade to the point of an unacceptable error rate increases, only gradual does the system degrade to the point of an unacceptable error rate. This property makes it more desirable than frequency Division multiple Access and Time Division multiple Access in cellular network that most have a fixed number of users.
