  2. Recommendations for the 3c Channel Model Subgroup Su-Khiong Yong Samsung Advanced Institute of Technology (SAIT), Korea Su-Khiong Yong, Samsung-SAIT

  3. Outline • Objectives • Channel representation • What do we have? • What are the possibilities? • How to move forward? • Conclusions Su-Khiong Yong, Samsung-SAIT

  4. Objectives • To make recommendations on how the channel modeling Sub-Group to move forward. • To clear some of the vague points that have been dragging the Sub-Group. Su-Khiong Yong, Samsung-SAIT

  5. Radio Channel “Single Directional” Channel Propagation Channel DOAs DODs M. Steinbauer, A.F. Molisch and E. Bonek, "The Double-Directional Radio Channel,” IEEE Comm. Mag, vol. 43, no. 4, Aug 2001. Su-Khiong Yong, Samsung-SAIT

  6. To get RC and SDC from PC But we can’t get PC from SDC or RC as well as SDC from RC ? Su-Khiong Yong, Samsung-SAIT

  7. 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 Su-Khiong Yong, Samsung-SAIT

  8. 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 *S. K. Yong, C. C. Chong and S. S. Lee, “Generalization and Parameterization of the mmWave Channel Models,” IEEE 802.15-05-0261-01-003c, Cairns, Australia, May. 2005. Su-Khiong Yong, Samsung-SAIT

  9. 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 Su-Khiong Yong, Samsung-SAIT

  10. 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 HornVertical polarized wave • Transmitting antenna 15 degree Horn, Receiving antenna 15 degreeHorn Vertical polarized wave • Transmitting antenna 30 degree Horn, Receiving antenna 15 degreeHorn Vertical polarized wave • Typical Japanese Office, NLOS • Transmitting antenna Omni,  Receiving antenna 15 degree HornVertical polarized wave • Transmitting antenna 30 degree Horn, Receiving antenna 15 degreeHorn Vertical polarized wave Su-Khiong Yong, Samsung-SAIT

  11. 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. Su-Khiong Yong, Samsung-SAIT

  12. 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 Su-Khiong Yong, Samsung-SAIT
