An optimal tradeoff formula between diversity gain and multiplexing gain was derived. The formula is a step decreasing and right continuous function,and the number of steps is equal to the number of receiving antennas. The diversity gain is relative to the block length, and can amount to the ...
In this case, precoding provides both diversity gain and array gain as both transmit antennas are used and the weights are selected such that the signals from the two antennas add coherently at the receiver. This results in a higher received carrier-to-interference ratio than in the absence of...
MIMO technology provides the system with the spatial multiplexing gain and spatial diversity gain. In spatial multiplexing, multiple antennas are used on the receive end and transmit end, and multipath components in spatial communication are used, allowing signals to be transmitted over multiple data ...
Such a multiple access in a unit of sub-channel may increase complexity but is advantageous in that frequency diversity gain and gain subject to concentration of power can be obtained, and forward power control can efficiently be performed. A slot allocated to each user is defined by a data ...
MISO configuration) and multiplexing gain is0. In the spatial multiplexing technique, each bit of the data stream (independent information) is multiplexed on three different spatial channels thereby increasing the data rate. Here, the diversity gain is0and the multiplexing gain is3(assuming ...
a plurality of OFDM symbols are used for 1-bit control signal transmission, by transmitting a CDMA modulated 1-bit control signal on a different OFDM symbol area through a different frequency domain, it is able to perform efficient transmission in aspects of resource efficiency and diversity gain...

PROBLEM TO BE SOLVED: To enable multiplexed information to stand compressing processing or the like by finely dividing an image into block images, performing down sampling, converting its frequency, changing a frequency components, inversely converting the frequency, performing up sampling and thereby re...
the first user may draw 8 W while the second user only need 2 W, and at a later time the first user may not need to transmit any more while the second user can access both transponders coherently to get 10 W equivalent “transponder power”; or a 3 dB more gain on equivalent EIRP...
