Dynamic IQ data compression using wireless resource allocation for mobile front-haul with TDM-PON [invited]


The time-division multiplexed-passive optical network (TDM-PON) architecture will efficiently accommodate densely deployed small cells in a centralized radio access network (C-RAN)-primarily based future radio access (FRA). C-RAN is a sort of mobile front-haul network, that connects multiple remote radio heads to a baseband unit pool by optical links. The desired optical bandwidth within the mobile front-haul of FRA is terribly large, so it's necessary to efficiently use the optical bandwidth by using in-part and quadrature-part (IQ) data compression techniques. This paper proposes an IQ information compression technique that dynamically reduces the desired optical bandwidth primarily based on wireless resource allocation, and provides TDM-PON with statistical multiplexing gain. Simulation results showed the achievable compression ratio of the proposed IQ knowledge compression technique. The feasibility of our technique was confirmed by experiments. The reduction in the common TDM-PON bandwidth was 50percent when there have been sixty mobile terminals, all of that needed zero.18 Mbps bandwidth.
