This paper studies the design and analysis of multiresolution vector quantization (MRVQ) for broadcast channels. Given a broadcast system with MRVQ, a random index assignment, and a coded broadcast channel, we first obtain a closed-form formula for the weighted end-to-end distortion (EED) of the system. Based on the formula, an iterative algorithm is then proposed for designing optimal MRVQ for the...
The layout design of complex engineering systems (such as satellite-module layout design) is very difficult to solve in polynomial time. This is not only a complex coupled system design problem but also a special combinatorial problem. The fitness function for this problem is characterized as multimodal because of interference constraints among layout components (objects), etc. This characteristic...
The topological design of local area network is a process to find the network with the best performance, minimum cost and highest reliability, under the objective and engineering constraints. The problem could be considered as a multi-objective optimization problem, owing to that it requires all kinds of network performances be optimized at the same time and keeps the cost minimum, and has been proven...
