Applications
The Viterbi decoding algorithm is widely used in the following areas:
- Radio communication: digital TV (ATSC, QAM, DVB-T, etc.), radio relay, satellite communications, PSK31 digital mode for amateur radio.
- Decoding trellis-coded modulation (TCM), the technique used in telephone-line modems to squeeze high spectral efficiency out of 3 kHz-bandwidth analog telephone lines.
- Computer storage devices such as hard disk drives.
- Automatic speech recognition
