Принадлежит: Hong Kong Applied Science and Technology Research Institute ASTRI

The present invention relates to a method of channel estimation comprising two major steps. The first step is the least-squared and minimum mean-square error (MMSE) estimations on the pilot resource elements to generate the channel response estimates at the predefined pilot locations. The second step of the channel estimation, which utilizes the results from the first step to compute the channel response estimates for the remaining resource elements, comprises the following three operations: (i) averaging of each pair of adjacent pilot resource elements in the frequency direction to obtain the channel response estimate of the resource element in the middle of those two pilot resource elements; (ii) MMSE interpolation in the time domain for all the sub-carriers containing pilot signals; and (iii) linear interpolation in the frequency direction for all the sub-carriers not containing any pilot signals.

A thermal interface material provides thermal conduction or thermal dissipation across an interface, using a three-dimensional interconnected porous graphene (3D-IPG) foam structure. The 3D-IPG foam structure is constructed of three-dimensional interconnected graphene sheets formed as a plurality of monolayers, and having an flexible interconnection architecture. The flexible interconnection architectures allow the 3D-IPG to maintain a high interfacial thermal conductance by the 3D-IPG filling a gap between a heat source and a heat sink across the interface, and by capping small features up to nanoscale roughened surfaces.
