trellis code modulation การใช้

• Among many contributions to the theory of data transmission, he invented trellis coded modulation.
• SCCC codes were further analyzed in " Serial Turbo Trellis Coded Modulation with Rate-1 Inner Code ".
• Earlier in his career, Gitlin led the team that created the first V . 32 / V . 34 duplex, high-speed modems that used echo cancellation, fractionally spaced equalization, and trellis coded modulation.
• In telecommunication, "'trellis modulation "'( also known as "'trellis coded modulation "', or simply "'TCM "') is a modulation scheme that transmits information with high efficiency over band-limited channels such as telephone lines.
