Code Division Multiple Access
A spread spectrum approach for the digital transmission of data/voice over radio frequencies. Sound bits are digitized and the data is split into data packets that are encoded with unique identification tags. All of the data/voice is sent over a spread range of radio frequencies. The cell phone or data device receives all of the data packets but only re-assembles those packets with the correct code and transforms the broken-up bits of data into useful sound and data. This allows more traffic for a finite number of available frequencies than analog or the other digital standards.
My LG phone does CDMA, TDMA, and GSM, as well as analog modes.

Automatic Link Establishment (station)
In high-frequency (HF) radio, the capability of a station to make contact, or initiate a circuit, between itself and another specified radio station, without human intervention and usually under emergency conditions. ALE stations are generally computer-controlled.
The Air Force has ALE frequencies in the 11 and 19 MHz bands.

SSB is a highly efficent modulation mode and is widely used for HF communications.
