The basic idea of PDMA is that collocated DP transmit-antenna transmits
two independent data streams to different UEs simultaneously by using vertical and horizontal transmit-antennas.
On the other hand, the single-polarized massive MIMO systems perform higher average throughput for XPD = 15 dB since a higher level of XPD represents the higher directivity between transmit
and receive antennas.
and [S.sup.[j.sub.k[bar.L]]] is the 1 x L row channel vector from the L transmit
antennas to the kth user with subset [S.sup.j]; [([S.sup.[j.sub.k[bar.L]]]).sup.2] can be expressed as
A phased- MIMO radar system with the 20 transmit
and 20 receive antennas are considered.
Assume [[omega].sub.opt] [member of] [C.sup.M x 1] is the transmit
optimum weight vector generated by , then the transmit
antenna pattern for mechanical distortions of phased array antenna is given by
When resolving the Anopheles gambiae evolutionary history, the scientists identified breaks in DNA that lead to new chromosomal arrangements, and used these rearrangements to demonstrate the repeated evolution of the ability to transmit
a parasite, in a back-and-forth fashion.
In this case, a positioning system with fibre optic light buoys and an above-water telecommunications system optically transmits
and receives information to and from the tele-submersible.
Oki expects that the compact and light encoder will be used to transmit
IP video via satellite, paving the way for the development of a portable live streaming system.
With a shading coefficient as low as 0.51, some reflective films block significant heat but many transmit
as little as 15% of the visible light.
This can cause transmit
degradation, tune fail, and burn damage to the RF cable and the power amplifier coupler.
Black & Decker of Hampstead, Md., introduces three new laser levels that transmit
straight, level lines, eliminating the need for chalk lines, carpenter levels or straight edges.
(Microsoft does not transmit
software updates by e-mail.)
Though the four tire contact patches transmit
all of the forces that make up ride and handling performance, tires themselves have been left out of the rapid vehicle electronification that's taken place in the past few years--until now.
The numbers are frightening: Almost 75% of sexually active adults have transmitted or will transmit
human papillomavirus to a sexual partner.
If multiple nodes transmit
at the same time, a packet collision occurs and the nodes must reschedule the transmission of the packets.
