In a code-division multiple access (CDMA) system with N = 8 chips, the maximum number of users who can be assigned mutually orthogonal signature sequences is _______.

1. 2
2. 4
3. 8
4. 16

Correct answer: 8

Solution

In a CDMA system, the maximum number of users that can be assigned mutually orthogonal signature sequences is equal to the number of chips available. Since there are 8 chips, up to 8 users can be accommodated with unique sequences that do not interfere with each other.
