Communication Systems

Library Communication Systems is designed for modelling and analysis of various communication systems. It provides ready-made blocks for modelling communication channels, filters, receivers, signal sources, modulation and demodulation, including phase modulation, OFDM and other methods.

The main tasks of the library include design and optimisation of transmission and reception systems, simulation of different types of communication channels and analysis of their characteristics. The library helps to create very accurate models of communication systems, simulate and test various modulation and demodulation techniques, and analyse the performance of communication systems in different environments.
