For the frequency difference of arrival(FDOA) estimation in passive location, this paper transforms the frequency difference estimation into the radial velocity
Impressive advances in space technology are enabling complex missions, with potentially significant and long term impacts on human life and activities. In the v
At present, mud pulse transmission systems are widely used in downhole data transmission. But the systems are very low in transmission efficiency, only 5-10 bit
There are many factors that influence the propagation of electromagnetic wave in the sand-dust storm environment, the scattering effect of dust particle is one
Coherent detection in OFDM systems requires accurate channel state information (CSI) at the receiver. Channel estimation based on pilot-symbol-assisted transmis
