Question

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 ____

Answer 1

Spreading factor( SF) = chip rate/symbol rate

This if a single symbol is represented by a code of 8 chips

Chip rate =80×symbol rate

*.F ( Spreading Factor) = (8 symbol rate)/(symbol rate) = 8

Spread factor (or) process gain and determine to a certain extent the upper limit of the total number of uses supported simultaneously by a station.
