    • Analysis of RF power optimisation for SCM-based free space optical systems for IM3 

      Lim, W.; Ghassemlooy, Z.; Kim, K. (2011-09-15)
      The focus of this reported research is on the optimisation of input RF power in SCM-based free space optical (FSO) systems to minimise the average BER because higher input RF power does not always provide FSO systems with ...

    • Next generation PONs with wireless backhauling 

      Milosavljevic, M.; Kourtessis, P.; Lim, W.; Senior, J.M. (Institute of Electrical and Electronics Engineers (IEEE), 2011)
      This paper is tackling the issue that stem from the coexistence of diverse technologies, such as emerging OFDMA-PON and WiMAX/LTE, within the same infrastructure. It outlines the key requirements that need to be fulfilled ...

    • QoS aware MAC protocol for OFDMA-PON 

      Lim, W.; Kourtessis, P.; Milosavljevic, M.; Senior, J.M. (Institute of Electrical and Electronics Engineers (IEEE), 2011)
      A quality of service (QoS) aware medium access control (MAC) protocol is presented for next generation OFDMA-PONs. The end-to-end delay and network throughput are investigated in the presence of class-of-service and ...
