Path metric memory management forminimising interconnections in Viterbidecoders
S.-Y. Kim, Hidong Kim, In‐Cheol Park · Electronics Letters · 2001
To simplify the interconnection between processing elements and path metric memory banks in Viterbi decoders, a new path metric update scheme is proposed based on two techniques, named swapped state grouping and swapped computing. The proposed scheme leads to a simple interconnection consisting of 2 × 2 switches.
