dvbshout takes an MPEG transport stream from a DVB card, extracts audio channels from stream, and sends the audio to an Icecast / Shoutcast server. It had only been tested with DVB-S, but should also work with DVB-C and DVB-T. Example run: ./dvbshout dvbshout.conf DVB card name: "Philips... Platforms: *nix

GPS::SpaceTrack is a package for calculating the position of GPS satellites. SYNOPSIS use GPS::SpaceTrack; my $obj=GPS::SpaceTrack->new(filename=>"gps.tle"); print join("t", qw{Count PRN ELEV Azim SNR USED}), "n"; foreach ($obj->getsatellitelist({lat=>38.870997, lon=>-77.05596})) { print...

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... Platforms: Matlab

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication. Platforms: Matlab

The zip file contains1. A 128x256 Regular (3,6) H matrix (if you need to simulate other codes, need to write your own code for generating those parity check matrices). The file '128x256regular_v6.mat' is for those using Matlab 6.5.2. Files for LDPC code simulation over the AWGN channel.3.... Platforms: Matlab

ALAMOUTI performs Monte-Carlo simulation and estimates Bit Error Rate (BER) of Alamouti Scheme [1] over Rayleigh channel. The scheme presumes 2 transmit (Tx) and arbitrary number of receive (Rx) elements. If Rx=1 (one receive element) the ALAMOUTI is transformed to the order 2 transmit diversity... Platforms: Matlab
