7zX is a file archiver with high compression ratio. Compression ratio results are very dependent upon the data used for the tests. Usually 7zX compresses to 7z format 30-70% better than to zip format, and 2-10% better than most of other zip compatible programs. 7zX currently supports tar, zip,...

It can be used also for computing the BER (bit error ratio) for different Eb/N0 in an AWGN channel.MSK stands for Minimum Shift Keying. Requirements: - MATLAB 7 or higher

The two-step noise reduction (TSNR) technique removes the annoying reverberation effect while maintaining the benefits of the decision-directed approach. However, classic short-time noise reduction techniques, including TSNR, introduce harmonic distortion in the enhanced speech. To overcome this...

This simple m-file plots the Soft Handover probability as a function of the Soft Handover Threshold value used in the UTRA Soft Handover Algorithm. The relationship has been dertived by taking the ratio between the Cell area where Soft Handovers are enabled and the total Cell area.

The MATLAB program simulates binary frequency shift keying (BFSK) at baseband through Monte Carlo method. The goal is to simulate bit error rate (BER) over an additive white Gaussian noise (AWGN) channel. For realizing that, the effect of noise is represented in the baseband with Gaussian random...

This script demonstrates the influence of range reduction algorithm at low bitrate encoding using JPEG encode. The range [0-255] of pixel values is mapped to [64-235] in this script using a look-up-table. Subsequently, the file is compressed to achieve the same bit-rate (file size) as that of the...
