Let's consider for each case whether the receivers B and D can decode the transmission correctly....

What the receivers B and D will decode:

∞ 1 / Rc(τ) = --- | pi(t) pj(t+τ) dt (See: click here) T / 0 |
The function pi(t) and pj(t) are the wave forms of the two PN codes.
(Don't worry, you don't need to know the details of correlation - it's there for completeness sake....)
|
Intermediate values (between 0 and 1) indicate how much the codes have in common.

This form of multiplexing using PN codes is called:
