THE IMPLEMENTATION OF AN IRREGULAR VITERBI TRELLIS DECODER

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The Viterbi algorithm has uses for both the decoding of convolutional codes and the detection of
signals distorted by intersymbol interference (ISI). The operation of these processes is
characterized by a trellis. An ARTM Tier-1 space-time coded telemetry receiver required the
use of an irregular Viterbi trellis decoder to solve the dual antenna problem. The nature of the
solution requires the trellis to deviate from conventional trellis structure and become time-varying.
This paper explores the architectural challenges of such a trellis and presents a solution
using a modified systolic array allowing the trellis to be realized in hardware.
