Digitized radio over TDM-PON system with bandwidth reduction technique using wireless resource allocation

We propose a novel data bandwidth reduction method based on wireless resource allocation for digitized radio over a TDM-PON system. The proposed method reduces the sampling frequency of each BBU-RRU link with minimal degradation in wireless signal quality and the provision of a statistical multiplexing gain. Simulations show that the required PON bandwidth is reduced by 30% when there are 68 mobile terminals.
