Digital Communications Library

Communication library focused on channel equalization. It doesn't have a definite goal and will be updated as needed.

Current Modules

Adaptive Filers

LMS, NLMS
RLS

Equalizers

Static Linear Equalizer: ZF, MMSE (Wiener) tap solution

Modulators

BPSK

Random Variable (RV) Generators from Uniform Distribution

Gaussian RV
Rayleigh RV
Nakagami-m (m can be choosen integer or half-integer)
Gamma RV
Generalized K RV

Examples

End-to-end Linear Equalizer comparison. Used techniques: ZF, MMSE and LMS
Equalizer comparison based discrete channel model (still developing)
QPSK BER simulation on fading channel

Test

Currently ipynb files are used for testing

TODO

More equalizers, DFE, MLSE and Machine Learning based equalizers
Using a test framework
Various (de)modulators such as QPSK, PSK, DPQSK
Add references

Known Issues

In equalizer module, filter delay mechanism seems unhealty
