http://www-video.eecs.berkeley.edu/papers/avz/Neural%20net-based%20%20IEEE%20Com%2092.pdf WebIt is shown that the standard Van der Lugt filter can be used as an incoherent processor if appropriate modifications are made to its amplitude point-spread functions. In the proposed system the problems associated with realizing bipolar impulse responses are shifted to electrooptic detection of the desired signal on a constant bias level. When compared to …

WebThe Matched Filter To motivate this linear processor, let us start with a very simple sequential communication scheme: we send independent information bits at difierent time instants, butinterleave L¡1 zeros between every information bit. In other words, we send information only once inL time samples. Webtypically consists of a sediment filter, carbon filters, and an RO system membrane. RO systems force water through the membrane under pressure, leaving the contaminants at …
Web6.4.2Matched filter detection method. The matched filter(MF) technique is an optimum method to sense availability of spectrum since the MF can maximize the SNR even if … Web158 4.1.1.2 Matched–Filter Demodulation Instead of generating the {rk} using a bank of N correlators, we may use N linear filters instead. We define the N filter impulse responses hk(t) as hk(t) = f∗ k(T −t), 0 ≤ t ≤ T where fk, 1 ≤ k ≤ N, are the N basis functions. The output of filter hk(t) with input r(t) is yk(t) = Zt 0
