Signal transmission.

Signal transmission consists of the following steps:
1. A pseudo-random code is generated, different for each channel and each successive
connection.
2. The Information data modulates the pseudo-random code (the Information data is
“spread”).
3. The resulting signal modulates a carrier.
4. The modulated carrier is amplified and broadcast.
Signal reception consists of the following steps:
1. The carrier is received and amplified.
2. The received signal is mixed with a local carrier to recover the spread digital signal.
3. A pseudo-random code is generated, matching the anticipated signal.
4. The receiver acquires the received code and phase locks its own code to it.
5. The received signal is correlated with the generated code, extracting the Information
data.
