A compensation-based user scheduling (CBUS) for multiuser multi-input multi-output (MU-MIMO) systems with delayed feedback channel state information (CSI) is proposed. To cope with the great performance degradation caused by imperfect CSI in the selective transmission/ selective combining (ST/SC) transceiving systems, we propose the CBUS algorithm, which can effectively alleviate the effect of time...
Noises are inevitable when mining software archives for software fault prediction. Although some researchers have investigated the noise tolerance of existing feature selection methods, few studies focus on proposing new feature selection methods with a certain noise tolerance. To solve this issue, we propose a novel method FECS (FEature Clustering with Selection strategies). This method includes...
The human body balance measurement and analysis system ask for high precision to the center of gravity. This article in view of noise filter problem, analyze the insufficiency of commonly used data smoothing method and the classics RLS algorithm, proposed one kind of improved RLS adaptive filtering algorithm, the practical application effect is extremely ideal.
Coal science and technological innovation investment is economic activity that involves local governments, enterprises and other behavior subjects. These subjects influence and restrict mutually to maximize their utility. The paper used game theory and constructed a model to analyse the relation among enterprises. Finally, some important conclusions were drawn in the paper. And the most important...
A pilot-aided scheme for the parameter estimation in Paired Carrier Multiple Access (PCMA) satellite communication systems is proposed in this paper. Recently, the asymmetric application mode of PCMA, which is more efficient and pragmatic than the symmetric mode, has been studied with great interest. In our research, carefully selected pilot sequences have been inserted into the frame in an attempt...
In this paper, we propose a parallel interleaver design for interleave-division multiple-access (IDMA) systems. The advantages of our approach are the low complexity induced from an algebraic solution and the parallel processing with negligible performance degradations against random interleavers. It is specially suitable for parallel implementation of multiple user detections and decoding of IDMA...
The increase in user amount and voice traffic puts a huge pressure on GSM/EDGE networks especially within populous countries. A newly proposed concept, multi-user reusing one slot (MUROS), would help operators in densely populated cities to alleviate the strain on their networks. The key idea of MUROS is to multiplex two or more users onto one time slot. We improved one downlink (DL) MUROS solution,...
GSM network is seeing its greatest expansion because of the growing demand for mobile voice services in emerging markets recently. A newly proposed technology, multiuser reusing one slot (MUROS), would help operators in densely populated cities to alleviate the strain on their networks. The concept of MUROS is based on multiplexing two or more users onto one time slot without degrading the speech...
