Abstract
In this paper, we consider the downlink in cloud radio access networks (C-RAN). In the network, multiple users are served by a cluster of remote radio heads (RRHs), which are connected to the building baseband units (BBU) pool through the fronthaul links with limited capacity. We propose a rateless coded transmission scheme which the rateless coding, precoding, signal compression are jointly designed for the C-RAN downlink. In order to approach the theoretical limit, we further optimize the degree profiles of rateless code based on extrinsic information transfer (EXIT) function analysis.
