In this paper, maximum rate interference alignment (MR-IA) algorithm is proposed for multi-cell downlink interference systems. Based on the researches on distributed interference alignment (IA) algorithms, the proposed algorithm can further enhance the sum rate. In this scheme, the precoding matrices are optimized by searching precoding alone the gradient ascent direction of throughput. In this process,...
Wherein the framework of block compressive sensing sampling of images, an l_p norm minimization algorithm is proposed. The proposed algorithm is memory efficient as we just need to store a block diagonal sensing matrix for sampling the small blocks divided from an original image. The whole image is reconstructed with an l_p norm minimization. To improve the quality of the reconstructed images and...
Deterministic design optimization (DO) may lead to unreliable designs due to not taking into consideration uncertainties. In recent years, DO under uncertainty has attracted more and more attention. In DO practice, both aleatory and epistemic uncertainties may exist, furthermore, the two types of uncertainties may affect both the objective function and the constrains of the optimization problem. In...
