Trellis code is a method used in digital communications to improve the reliability of data transmission over noisy channels. It combines convolutional coding with the concept of a trellis diagram, which represents the state transitions of a coding system. This encoding technique allows for efficient error correction by leveraging the structure of the trellis to decode received signals more accurately. Trellis codes are particularly effective in applications like wireless communications and data storage.
