Abstract: |
The implementation of a high-speed Viterbi decoder of the (2,1,7) convolutional code is described. Not only a parallel structure is used in designing the Add-Compare-Slect(ACS) unit, but also a series of simplified measures are a dopted. The maximal data output speed of this decoder is 160Mbps. |
