But we can’t get PC from SDC or RC as well as SDC from RC ?

What do we have so far?
IBM data  Radio Channel
IMST data  Single Directional Channel
NICT data  Single Directional Channel
NICTA proposed measurements  Single Directional Channel
Umass proposed measurements  Single Directional Channel

8. What Are the Possibilities?

What Are the Possibilities?
Double directional channel is complex and not easy to deal given that we have limited time left and amount of resources we have.
Radio channel – We have the data and there are plenty of results to be captured from the literature, see an overview*.
Single directional channel – We have the data too and this is the way we should focus and work on it

Single Directional Channel
SDC CIR can be captured by
rotating single antenna in a small interval over 360o,
virtual antenna array
antenna array
With SDC we can take into account for different antenna setups

Different Antenna Setups
Based on the data we have e.g. NICT data
Typical Home (Japanese living room) LOS
Transmitting antenna Omni,  Receiving antenna 15 degree Horn Vertical polarized wave
Transmitting antenna 15 degree Horn, Receiving antenna 15 degree Horn Vertical polarized wave
Transmitting antenna 30 degree Horn, Receiving antenna 15 degree Horn Vertical polarized wave
Typical Japanese Office, NLOS

To account other configurations
The CIRs obtained, deconvolve the CIRs with the original antenna pattern and then convolve with the new antenna pattern.
Only applicable to one link end.

Conclusion
We should focus on the single directional channel given that
Data availability
Less complex than the double directional but more useful than the radio channel for our performance evaluation
