Subband

The fn will calculated subband energes as given in the att tech paper of ruhi sarikaya and others. the fn also calculates the DCT part. using this fn and other algo for pattern classification(VQ,GMM) speaker identification could be achived. the progress in extraction is also indicated by progress...

This is a toolbox to compute the subband structure of the quantum cascade lasers without conduction band nonparapolicity effect. Platforms: Matlab

Sub band processing is based on splitting the frequency range into M segments (subbands),which together encompass the entire range. Each subband is processed independently, as called for by the specific application. The subbands are recombined after processing, to form an output signal whose... Platforms: Matlab

There are many techniques used to deal with the problem of high PAPR in OFDM systems. An effective one is the Partial Transmit Sequence. It is simulated for QPSK modulated 64-subband OFDM system.Moreover, a .mat file of 100000 such OFDM symbols is available. Platforms: Matlab

These algorithm are based on the G722 standard..You need a fixed-point toolbox to run it..Read the Readme.m first.It is what i did in a project of a course Platforms: Matlab

Calculates the average log-spectral distance between CLEAN and NOISY signals. It has the capability of calculating this distance for a specified sub-band as well. This measure is used for evaluation of processed speech quality in comparison to the original speech. Platforms: Matlab

Calculates the average log-spectral distance between CLEAN and NOISY signals. Has the option of calculating this distance for speech active periods only. Also you can select a frequency range to study the distance in a sub-band. Platforms: Matlab
