  Certain deterministic interference channels have been shown to accurately
model Gaussian interference channels in the asymptotic low-noise regime.
Motivated by this correspondence, we investigate a K user-pair, cyclically
symmetric, deterministic interference channel in which each receiver
experiences interference only from its neighboring transmitters (Wyner model).
We establish the sum capacity for a large set of channel parameters, thus
generalizing previous results for the 2-pair case.
