摘要:
In a method for selecting a transmission target terminal in a zero-forcing beamforming algorithm, information about a channel capacity of each terminal is received from all K terminals. A terminal with a largest channel capacity is selected as an initial transmission target terminal. A determination is made as to whether the number of currently selected terminals, i, is equal to the predefined number N. If the number of currently selected terminals, i, is different from the predefined number N, information about channel capacities of remaining terminals except previously selected transmission target terminals is received until i is equal to N and a terminal with a largest channel capacity is selected as a transmission target terminal.

摘要:
A self-adaptive multiple-input multiple-output (MIMO) transmission/reception system includes a transmitter provided with a serial-to-parallel converter, channel encoders, a plurality of constellation mappers, and transmission power controllers, and a receiver provided with a transmission scheme selection device, a zero forcing/minimum mean square error (ZF/MMSE) detector, reception power controllers, constellation demappers, channel decoders and a parallel-to-serial converter. The transmission scheme selection device generates information regarding plural sets of information to be used, a constellation mapping scheme and transmission power and transmits the generated information to the associated units of the transmitter and receiver, thereby controlling the number of sub code streams, the constellation mapping scheme and the transmission power. The system and method provide superior performance and require minimal feedback information.

摘要:
An injection locked transmitter for an optical communication network includes a master seed laser source input substantially confined to a single longitudinal mode, an input data stream, and a laser injected modulator including at least one slave laser having a resonator frequency that is injection locked to a frequency of the single longitudinal mode of the master seed laser source. The laser injected modulator is configured to receive the master seed laser source input and the input data stream, and output a laser modulated data stream.

In accordance with the present invention, novel superparamagnetic magneto-dielectric polymer nanocomposites are synthesized using a novel process. The tunability of the dielectric/magnetic properties demonstrated by this novel highly-viscous solvent-free polymer nanocomposite that is amenable to building 3D electromagnetic structures/devices by using processes such as 3D printing, compression molding or injection molding, when an external DC magnetic field is applied, exceeds what has been previously reported for magneto-dielectric polymer nanocomposite materials.
