Transmitter detection technique is further classified into energy detection, matched filter
detection and Cyclo-stationary feature detection.
K]] denotes the output of the AWGN from each user's corresponding matched filter
, while the random variable nk is normally distributed and E[[n.
Whereas, the matched filter
technique has shown good performance and high accuracy at the expense of more complexity and requires perfect knowledge.
Let us summarize some properties of this matched filter
The matched filter
easily generalizes to communications receivers, incorporating channel estimation and equalization.
In Figure 6, the results of the matched filter
are also plotted.

range processing," Proceedings of IEEE Radar Conference, 446-451, 2003.
A basic matched filter
processing blockset was designed as shown in Fig.
2](t) are the matched filter
outputs for the ideal and erroneous pulses, respectively.
The proposed receiver consists of a matched filter
followed by a blind [lambda]-combiner that is capable to estimate the value of [lambda] blindly and adaptively for each received bit.
FIR mainly functions are as a shaping filter for the whole signal channel and as well as a matched filter
when there is need.
Peng and Zhao used a method known as the matched filter
technique, rather than the standard technique to examine the aftershocks.
