Application of the symmetrical and non-symmetrical models for innovative coded design of signals
(Видавництво Львівської політехніки, 2012) Riznyk, Volodymyr
In this paper the innovative coded design techniques for improving the quality indices of data coding (e.g. self-checking codes) based on the “perfect” symmetrical and non-symmetrical relationships, namely the concept of Ideal Ring Bundles (IRBs), are given. These design techniques make it possible to configure high performance coded systems and design of signals for communications and radar, visual coding systems with respect to redundancy, signal reconstruction and low side lobe antenna design.
