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: n this paper, a new dynamic noise reduction
algorithm is proposed based on time-variety filter (TVF), which
can be implemented in both time and modified discrete cosine
transform (MDCT) domain. In time domain, an IIR filter with
changeable bandwidth is for the TVF. In frequency domain,
combined with MDCT transform, the noise is suppressed in
MDCT domain. A few experiment results reveal that the
algorithm retains the noise-suppressing performance with low
delay and algorithm complexity.
