Abstract
The throughput of reduced-state sequence estimation (RSSE) is limited by a substantially longer recursive loop than the add-compare-select function, which is the bottleneck of Viterbi decoding. This paper reformulates the RSSE algorithm to allow pipelining of the branch metric and decision-feedback computation. With this approach the critical path is shortened to the order of the add-compare-select function with only modest increase in hardware
