Testing of the 2.4 GHz Band Spread Spectrum Sound Transceiver Unit Using an Elastic Type SAW Convolver
The spread-spectrum communication method was developed for military communications during World War II. It is favored mostly for its resistance to interference and keeping signal security. When a signal is spread with a coded "key", redundant information is transmitted with lower power throughout a given RF band. Since interference occurs at very specific frequencies, it is difficult for it to disrupt the signal at each frequency within the band. Because of these characteristics the method has been used widely ranging from commercial to military applications such as an automobile navigation system (with using GPS), a LAN system, a sound system, and the space shuttle communication.
