The main research topics are: multiple input multiple output (MIMO) technique, impulse radio, and transmission performance comparison among several high rate transmission techniques. In MIMO, we have established the channel measurement system for MIMO, analyzed the channel capacity for MIMO, proposed channel estimation algorithms for MIMO, and studied the signal processing for wideband MIMO. In impulse radio, we will establish the channel measurement system for impulse radio, study the effect of antenna ’s frequency response on the transmission performance of impulse radio, and investigate the near body effect of impulse rad io. In high rate transmission we have compared the highest data rates that can be achieved by different techniques such as by using directive antennas, equalizers, OFDM, MIMO, or combinations of the above techniques.application/pdf302530 bytesapplication/pdfzh-TW國立臺灣大學電信工程學研究所後第三代行通訊技術多輸入多輸出脈衝無線電技術超寬頻信號高速率傳輸技術B3GMIMOImpulse RadioUltra Wide-Band SignalHigh Rate Transmissionreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20261/1/912213E002108.pdf
