This application contains topologies and data files for simulating simple LMS adaptive filters and multi-channel fast transversal adaptive filter and multi-channel LMS adaptive filter.
Complete simulation of a hierarchical voiceband codec with 8 bit u-law companding, IIR digital filtering filtering, sampling and recovery.
A digital communication link with QPSK modulation, Nyquist pulse shapping, addive noise and BER computation. A PERL script is provided that shows how to setup BER simulations with the topology files executed in batch mode.
Frequency Shift Keying with a DCO in the modulator and a digital PLL in the receiver.
First order and second order Delta Sigma analog to digital converter.
