ABSTRACT:
A configurable Viterbi decoder to decode a coded signal for inclusion in a radio receiver for implementing the physical layer receiving function (PHY) of a wireless data network. The decoder includes a branch metric generator with an input to the coded signal, an ACS subsystem coupled to the branch metric generator, and a survivor memory unit coupled to the ACS subsystem. The decoder includes a plurality of outputs each providing a decoded version of the input signal decoded to a distinct decision depth such that the Viterbi decoder is programmable to decode the signal to one of a plurality of decision depths.
