| Abstract: | This paper investigated the very large scale integrate circuit(VLSI) implementation of turbo decoder.The add-compare-select-offset(ACSO) calculation unit that is used to calculate the state metrics was considered in detail.The slide-window technique was applied to the MAP decoding scheme.And a general architecture of turbo decoder was described.The simulation result shows that described scheme works well and can fulfill the requirements. |
