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
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
The Framework & System Model • Signal transmitted through antenna k: • :determines multidimensional space- time modulation format.
Modulation Format 1、Orthogonal transmit antenna format (OTA) 2、Aggregate transmit antenna format (ATA) 3、Partially orthogonal transmit antenna format (POTA) 4、Other allocation
Discrete Channel • Transmit orthogonal group: TOG
Comparison of Space-Time Mod. Methods in Multipath Channels • Shannon Capacity • The link SNR in the term
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”
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.
