Abstract
The purpose of this project is to investigate the advanced technology
for B3G (beyond the third generation). 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.
