A new non-orthogonal space-time-frequency code (STFC) was proposed. In conjunction with orthogonal frequency-division multiplexing (OFDM), it is appropriate for
In this paper,we analyze the scheme of Space-Time Coded BeamForming(STC-BF)for the downlink of DS-CDMA system over frequency-selective fading channels and give
In order to maximize the average throughput and minimize the transmission slot delay in wireless Ad Hoc networks,an optimal topology-transparent transmission sc
With the numerical simulation and high-speed camera, a series of images of dispensing of rod from different devices were obtained. The process of dispensing of
BACKGROUND:Islet stem cells are more or less retained in the procedure of islet isolation and puriifcation, and are transplanted together with islet grafts. Ker
