This is the source code produced for the paper “Fast Time-Domain Volterra Filtering”, presented at the Asilomar Conference on Signals, Systems and Computers, 2016. It includes 16 implementations of time-domain Volterra filters together with testbenches for the verification of correctness and runtime. The 16 implementations result from the combination of 4 methods of traversing (nested-loop, combinatoric, lookup-table, hard-coded) with 4 methods of computation (direct1, direct2, reuse, horner).
