The main disadvantage of linear techniques, however, is that the number of simultaneously served single antenna users can be at most equal to the total number of transmit antennas.
However, it may not be unreasonable to assume that the cost-efficiency estimates of public sector STI care apply to those who are at most risk of acquiring or transmitting HIV, and therefore, are important for assessing and comparing the cost-efficiency and cost-effectiveness of the various HIV prevention strategies.
Therefore, in order to maximize the sum throughput, L ≤ 1, that is, at most one receiver can be transmitted jointly by the two transmitters, and each other receiver is transmitted only by some single transmitter, i.e., the optimization problem (4) can be reformulated as (5).
Note that, on average, according to definition (8) and for physical reasons the power leaked on the copolar dimension is at most equal to the power transmitted on the cross-polar channel.
Since S and D are always transmitting and receiving, respectively, there are at most 23 = 8 configurations of {δ i }.
For a conventional system based on ARQ mechanism, we consider the scenario where the packet can be transmitted at most by two transmission slots, i.e., only one retransmission.
Culex species, excluding Cx. p. quinquefasciatus from the Coachella Valley and Orange County, were most efficient at transmitting virus after exposure to the high dose and 14-day incubation period.
One map shows that in 2003, all but three states reported at least one person infected with the disease, which is most commonly transmitted by mosquitoes.
At that time, the causative agent was believed to be vaccinia virus (VACV) that was most probably transmitted by recently vaccinated children to the elephants.
