are optimal for detecting a known reference image in additive white Gaussian noise environment.
Extensively revised and updated, coverage includes description of the function of transmitters, antennae, receivers, matched filters
, and signal processors.
The received signal is first stripped of its cyclic extension and then passed through a bank of chip matched filters, as shown in Figure 1, where
is the chip matched filter for the pth sub channel, followed by chip rate (1/[T.
3 Optimum Detection, Space-Time Matched Filters
, and Beam Forming in Gaussian Noise Fields
Through that program, we recently developed a unique Fiber Bragg Grating-Artificial Reference Cell (FBG-ARC) technology for remote gas sensing based on novel modulated, tailored matched filters
and correlation spectroscopy for the NSF.
Patent #6,111,671 on August 29, 2000, for Matched Filters
for a Real Time Fingerprint Sensor and Verification System, filed November 18, 1999, as a divisional patent application of U.
It incorporates a 2-90 Mbps variable BPSK/QPSK/OQPSK receiver, dual 8-bit A/D converters, a phase/frequency recovery block, variable rate digital filters, square root Nyquist matched filters
, acquisition and tracking loops, and a DVB/DSS/Primestar compliant FEC decoder onto a single chip.
A matched filter response is easily calculated following the basis expansion.
m] (n) are the basis coefficients of the locally generated matched filter template.
The matched filter easily generalizes to communications receivers, incorporating channel estimation and equalization.
