Traditionally in CDMA system, selective rake receiver is the popular method of
detection. When used in DS-UWB system, the complex in door environment will
increase the channel paths. As the channel paths increase, the more fingers which are
part of Rake receiver will increase. It will be difficult for hardware implement when
consider the operation of channel estimation and Rake receiver. And it is unfavorable
for hardware design.
In this thesis, we will use partial Rake receiver to replace selective Rake receiver.
Channel estimation is implemented by template the receiver signals within 2 bit time
window length. The performance is acceptable and the hardware complexity is
reduced. When implement the channel estimation, we combine some blocks of
acquisition and channel estimation for reducing hardware complexity.
