Gives every user a unique digital code. Devices transmit across the same frequency at the same time, and the receiver uses the code to isolate the correct conversation.

: Building complex communications from individual samples, a key focus for SDR practitioners. 3. Wireless Channel Challenges

In 1948, Claude Shannon defined the theoretical limit of any communication channel: $$C = B \log_2(1 + \fracSN)$$ Where $C$ is capacity (bits/sec), $B$ is bandwidth, and $S/N$ is the signal-to-noise ratio. Building "from the ground up" is essentially the engineering pursuit to approach this Shannon Limit in the presence of the fading described above.
