A genetic algorithm based on small-world model (GA-SW) is developed for solving the scheduling and placement problem in FPGA. In this problem, a set of tasks with their own start times, execution times and deadlines is to be scheduled into the FPGA with the objective to minimize the total delay of tasks. The small-world network model possesses locality character, i.e., tightly local connections and...
Flexible optical channel data unit (ODUflex) is a new technique in the optical transport network (OTN) used to replace virtual concatenation (VCAT). For packet clients, it will be advantageous while ODUflex has the capability of hitless resizing like link capacity adjustment scheme (LCAS). A novel scheme is proposed in the paper for this purpose. The proposed scheme designs the new overhead (OH) and...
It is important to support the multicast in the OTN network since multicast services are becoming more popular and multicasting will result in the improvement of resource utilization rate. To support multicast in a cost-effective way, the multicast of OTN should be realized in electronic domain based on ODU-level rather than optical domain in our point of view. In order to implement multicast routing...
Multiple-input multiple-output (MIMO) receive antenna selection without channel state information (CSI) for linear detection is proposed in the presence of unknown interferences. This antenna selection technique is implemented based on training sample sequence by minimizing the Least Squares (LS) estimation error, which avoids the channel estimation. Since the high complexity of the exhaustive search,...
The antenna selection technology is introduced into the existing uplink Alamouti multi-user MIMO detection for a low hardware cost. A selection criterion maximizing the minimum user signal-to-noise-plus-interference-ratio (SINR) is proposed. To avoid the exhaustive search selection, a fast selection algorithm is further proposed that selects an antenna to maximize the minimum user SINR in each stage...
