- Abstract
- The receiver performance with the use of a space
time transmit diversity (STTD) scheme is more susceptible to
the accuracy of channel estimate than that without the use of
the STTD scheme since the despreading signals suffer from the
effect of crosstalk and the transmit power is equally divided
into multiple transmit antennas. As a result, the efficiency of
channel estimation in the WCDMA STTD system becomes an
important issue more than that in the non-STTD system. In this
paper, an adaptive channel estimator (ACE) is designed to
mitigate the performance degradation due to inaccurate
channel estimation. Numerical results show that the
performance improvement significantly increases with the use
of the proposed ACE, particularly when the channel condition
becomes worse.
