Description: NAME:
bpass
PURPOSE:
Implements a real-space bandpass filter which suppress
pixel noise and long-wavelength image variations while
retaining information of a characteristic size.
CATEGORY:
Image Processing
CALLING SEQUENCE:
res = bpass( image, lnoise, lobject )
INPUTS:
image: The two-dimensional array to be filtered.
lnoise: Characteristic lengthscale of noise in pixels.
Additive noise averaged over this length should
vanish. MAy assume any positive floating value.
lobject: A length in pixels somewhat larger than a typical
object. Must be an odd valued integer.
OUTPUTS:
res: filtered image.
PROCEDURE:
simple wavelet convolution yields spatial bandpass filtering.

Description: Radio-over-Fibre Technology for Broadband Wireless Communication Systems -The research in this thesis focussed on the feasibility of using both single-mode and
multimode fibres to distribute high-frequency microwave signals to simplified remote
radio antenna units. An alternative radio-over-fibre technique, termed Optical
Frequency Multiplication (OFM) has been investigated. OFM entails the periodic
filtering of a swept optical signal at the headend followed by photodetection at the
radio access unit. A low sweep frequency (e.g. 3 GHz) is used. After photodetection
at the remote radio access unit, high-frequency (>21 GHz) harmonic components of
the sweep signal are generated. The desired microwave signal is selected by means of
bandpass filtering, amplified, and radiated by the antenna. Modulated microwave
carriers are generated by intensity modulating the frequency-swept optical signal.
