In a direct sequence CDMA system, the chip rate is 1.2288 × 106 chips per second. If the processing gain is desired to be at least 100, the data rate:
1
must be less than or equal to 12.288 × 103 bps
2
must be greater than or equal to 12.288 × 103 bps
3
must be exactly equal to 12.288 × 103 bps
4
None of the above
