Consider three hosts A, B, and C using Code Division Multiple Access (CDMA) with chip length m = 4. They chips

are the following:

A: +1 -1 +1 -1; B: +1 +1 -1 -1; C: +1 -1 - 1 + 1

Show the resulting signal S when A transmits a 1 and C transmits a 0.

Discuss and show how we can infer from S that B did not transmit.
