CSL initiated a long-range program in spread-spectrum communication, which is now known as code-division multiple access, or CDMA. With spread-spectrum, a radio signal is spread over a wide range of frequencies - an effective way to hide the signal from an enemy.
Signal Design and Performance Analysis
CSL's spread-spectrum work led to widely used methods for signal design and the performance analysis of communication systems.
Researchers designed the synchronization sequence in the Army's SINCGARS spread-spectrum radio.
