Abstract
A base node seeks to receive to a broadcast. The base is too far away to observe the broadcast itself, and instead listens through a LAN to several helper nodes which can hear the broadcast. The helpers want to convey exactly what they hear back to base, but the LAN constrains the sum of the data rates from helper to base so the helpers must quantize. A capacity for the system exists but is very difficult to reach. Bounds are found on the capacity of such a system with channel state information available at the helpers and in interference environments where the receivers experience correlated noise. The bounds are tight when the LANs constraint is very high or low. Trials of the bounds reveal that while the systems capacity is stable varying the ratio of scattered-path to line-of-sight signal power seen at the helpers, strategies for achieving the capacity must change.
