8.6 Simulation Results and Discussions
In this section, simulation results are presented to show the effective-
ness of the proposed scheme. For the channel model and the physical
system model are implemented in MATLAB
. The link-layer perfor-
mance data is fed to network simulator, ns2 (version 2.34) [1]. We con-
duct simulations using the following settings. There are three RRHs
in the C-RAN. The maximum size of a cooperating set is 2. The wire-
less channel is Rayleigh fading channel, and the normalized Doppler
shift ranges from 0.01 to 0.06. The bandwidth is 45 KHz. The link
layer
