Orthogonal frequency division multiplexing passive optical network (OFDM-PON) has been considered a promising access solution to meet the variable bandwidth demand. In this paper, a novel scheduling for dynamic bandwidth allocation (DBA) at medium access control (MAC) layer is proposed for uplink transmission of OFDM-PON. In order to utilize the bandwidth efficiently, scheduling in four dimensions...
A simple, low cost and robust OFDM-PON symbol synchronization technology is proposed and experimentally demonstrated. The main idea of this algorithm is to make use of the periodicity of the OFDM symbol to achieve symbol and frame synchronization at the receiver. This technology is applicable for the OFDM-PON system as some simple subtraction is required but without any multiplication. Using the proposed...
