  1. Space-Time Coded Modulation for MIMO Systems 指導教授：黃文傑 老師 學　　生：曾凱霖 學　　號：M9121014 無線通訊實驗室

  2. Outline 1、 The Framework & System Model 2、 Comparison of Space-Time Mod. Methods in Multipath Channels 3、 Comparison of Space-Time Mod. Methods in Multipath Channels 4、 Conclusions

  3. The Framework & System Model • Signal transmitted through antenna k： • ：determines multidimensional space- time modulation format.

  4. Modulation Format 1、Orthogonal transmit antenna format (OTA) 2、Aggregate transmit antenna format (ATA) 3、Partially orthogonal transmit antenna format (POTA) 4、Other allocation

  5. Discrete Channel • Transmit orthogonal group： TOG

  6. Comparison of Space-Time Mod. Methods in Multipath Channels • Shannon Capacity • The link SNR in the term

  7. MIMO System Performance & Implementation Issues • Shannon limit does not provide a design of a high-capacity system. • Layering concept： BLAST V-BLAST D-BLAST R-BLAST • “STREAM System”

  8. Conclusions • The extent to which realistic wireless MIMO environments generate parallel independent channels. • How to exploit such propagation channels with small mobile terminals operated by batteries.
