Description: The main code is called "comparison of equalization schemes".
It uses functions, defined seperately to compute the bit error rate for different typs of equalizers.
That means times domain equalizer (TDE) with minimum mean square (MMSE) and zero forcing (ZF) algorithm,time domain decision feedback equalizer (DF_TDE) and linear frequency domain equalizer (FDE) with MMSE and ZF algorithms are used.For all simulations QPSK symbols and a tapped delay line channel with white gaussian noise are used.
Allthough the codes should be regarded as one package every single function can be of good use for other simulations.
With best regards,

Description: The problem of channel equalization via channel
identification (CEQCID) that has previously been considered by a
handful of researchers is explored further. An efficient algorithm
for mapping the channel parameters to the equalizers coeficients
is proposed. The proposed scheme is compared with a lattice
least squares (LS) based receivers. For the particular application
of the high frequency (HF) radio channels, we find that the
CEQCID has lower computational complexity. In terms of the
tracking performance, also, the CEQCID has been found to be
superior to the LS based receivers [4]. We emphasize on the
implementation of a fractionally tap-spaced decision feedback
equalizer (DFE) and compare that with the T-spaced DFE of
[4]. We show that the former is a better choice for the multipath
HF channel-The problem of channel equalization via channel
