Physical phenomena such as temperature, humidity, and wind velocity often exhibit both spatial and temporal correlation. We consider the problem of tracking the extremum value of a spatio-temporally correlated field using a wireless sensor network. Determining the extremum at the fusion center after making all sensor nodes transmitting their measurements is not energy-efficient because the spatio-temporal...
In this contribution, Space-Time Block Coding (STBC) Code Division Multiple Access (CDMA) system is simulated to investigate the effect of spatial correlation of Multiple-input multiple-output (MIMO) wireless channels. In practical situations the MIMO antennas are spatially correlated, due to the lack of spacing between them or weak scattering. The correlative model is considered for MIMO channel...
In order to take advantage of the correlation information among different acoustic units in speech recognition, a novel approach named Minimum Covariance based Spatial Correlation Transformation was proposed in, which achieves satisfactory performance. However, there are two issues of this approach which can still be improved, 1) the estimation of the transformation matrix; 2) the construction of...
