Link to Block Codes
Christian B. Schlegel, Lance C. Pérez · 2004
Block codes have traditionally been constructed and decoded in algebraic ways, which do not lend themselves easily to soft decision decoding. We will see in this chapter that block codes can also be described by a code trellis; therefore, all the decoding algorithms developed for trellis codes find application. We will further see that block codes can be constructed using a trellis approach and that families of long-known block codes reappear in a different light. This trellis view of block codes enabling soft decision decoding has spurred renewed interest in block codes, and brings block and trellis codes much closer together.
