To ensure that the selected MIMO cases are general, numbers of transmitting and receiving antenna ([N.sub.T], [N.sub.R]) vary from 1 to 4, as presented in Section 4; the adopted constellations vary from QPSK to 256QAM; and simulated channel status - H are randomly generated.
Nucleus45 is designed to deliver 18dBm output power to meet the most stringent linearity requirement for 256QAM modulation for 11ac without the use of any DPD techniques.
For some high-order modulation modes, such as 256QAM, we must increase the number of levels to guarantee the well performance of the algorithm.
CFIP Lumina uses modulations from QPSK to 256QAM and capacity from 17--366Mbps full duplex bidirectional traffic in 1+0 applications.
The WTM 6000 is also the first trunking radio in its class to support 256QAM Adaptive Coding and Modulation (ACM) to enable operators to achieve higher link capacities with smaller antennas, which in turn reduces tower loading and infrastructure costs.
