Sentence examples for based on four antennas from inspiring English sources

Finally, we deduce that there is no gain only for the case of an SFN with Alamouti MISO transmission based on four antennas.

Therefore, we can deduce that there is no gain in the case of an SFN- 2x1 Alamouti MISO transmission based on four antennas.

We model the reception based on four antennas from two pairs of antennas (A1, A2) and (B1, B2) representing an SFN network each one.

Moreover, an SFN based on four antennas (receiving from four antennas) has almost the same performance as SFN-2x1 Alamouti MISO.

More precisely, we have demonstrated that SFN or SFN-2x1 Alamouti MISO networks based on four antennas behave like a three-antenna SFN or SFN-2x1 Alamouti MISO networks, or three antennas SFN or SFN-2x1 Alamouti MISO networks operate like a two-antenna SFN or SFN-2x1 Alamouti MISO networks depending on the echo attenuation.

Thereby, we can deduce that the diversity reduces the notches compared to SFN network based on three antennas.

More precisely, this case has the same evaluation result as an SFN-2x1 Alamouti MISO network based on three antennas.

These results show clearly that in the transmission based on two antennas, there are the deep "notches" for an SFN transmission, which leads transmission cuts.

However, if the second echo (0.9Δ) is attenuated the SNR values tend towards those of an 2x1 Alamouti MISO technique network based on two antennas.

Thus, we can deduce that the diversity transmission based on two antennas eliminates the notches produced in an SFN network and improves the diversity gain.

These results show that if we attenuate one of the four antennas, an SFN-2x1 Alamouti MISO network tends to work as an SFN-2x1 Alamouti MISO based on three antennas only (second case studied).
