    摘要: This invention provides methods and systems for achieving high-specificity killing of targeted cells using Magneto-Electric Nano-Particles (MENPs) and functional or diagnostic imaging that detects changes at the cellular level. Embodiments comprise injecting into a patient's body manufactured MENPs that have a higher tendency to accumulate near or attach to targeted cells through one or more physical forces and/or biological mechanisms; and applying a magnetic field to the MENPs to generate an action that is sufficient to cause death of the targeted cells, and using an imaging apparatus to image or detect a specific property of the MENPs or changes in a property of the MENPs due to the coupling of the MENPs with their surrounding environment.

    摘要: This invention presents a method and apparatuses for wireless networking comprising one or more BS with Nbs antennas; two or more SCs in the range of a BS where a SC has Nsc antennas, uses Nsc1≤Nsc antennas for communication with a BS and uses Nsc2≤Nsc antennas for communication with one or more UEs; at the same time a BS transmitting DL signals to K SCs using multi-user transmit BF in a frequency channel, a SC simultaneously transmitting DL signals to one or more UEs in its range using the same frequency channel; and, at the same time a BS receiving UL signals from K SCs using multi-user receive BF in a frequency channel, a SC simultaneously receiving UL signals from one or more UEs in its range using the same frequency channel. Furthermore, beamforming using antennas on the SCs is performed to reduce the inter-SC interferences.

    摘要: This invention presents methods for MU-MIMO wireless communication systems comprising a BS with plural of antennas placed as a linear array or planar array, plural of UEs, for conducting two-level signal processing at the BS to reduce the system implementation complexity, i.e., the RF precoding/combination and the baseband precoding/detection, for the BS to obtain the second-order statistical information of the channel matrix of each UE to computing the RF precoding matrix through a much smaller number of pilots than that of the transceiving antennas at the BS, where the second-order statistical information of the channel matrix can be obtained through the uplink reference signals or downlink reference signals plus uplink feedback.
