For the issue of resource allocation in a heterogeneous multi-user downlink OFDMA system with both delay-constrained (DC) and non-delay-constrained (NDC) traffic, this paper proposes suboptimal joint subcarrier and power allocation (JSPA) for channel-aware queue-aware(CAQA) scheduling. The objective is to maximize the sum of all NDC users' logarithmic utility functions (achieving proportional fairness)...
We propose and demonstrate a bandwidth-efficient overlay scheme in which a DSB (500 Mb/s) or SSB (1 Gb/s) OFDM-based video signal is superimposed over a 1.25 Gb/s times N WDM PON. Selective delivery is achieved by simply controlling individual transmitter laser biases at the central office. For subscribed customers, the optimal bias condition was obtained by observing power penalty changes for the...
We propose and demonstrate an optical-wireless integrated transmission scheme. Results show PON signal suffered only 0.3 dB power penalty and bit error rate of less than 10-6 for OFDM signal was achievable before FEC.
