Abstract
This paper presents the implementation of the Fast Walsh Hadamard Transform (FWHT) in sequence
ordered method, in order to minimize the interference due to two users trying to transmit at the same time,
and an attempt has made to simulate them. The simulations designed satisfy most of the requirements of
the parameters mentioned in the 3GPP specifications. The main objectives of this paper are to construct a
model using MATLAB 7.4.0(R2007a) to illustrate the simulation.
In image processing and pattern recognition the motivation for using transforms other than Fourier is
either to reduce computation time for a given resolution, or to increase resolution without increasing the
length of the computation time and to minimize the hardware resources. Fast Walsh-Hadamard Transform
has been used effectively to satisfy these requirements.
