Blind Recognition Algorithm of Turbo Codes for Communication Intelligence Systems
Turbo codes are widely used in land and space radio communication systems, and because of complexity of structure, are custom in military communication systems. In electronic warfare, COMINT systems make attempt to recognize codes by blind ways. In this Paper, the algorithm is proposed for blind recognition of turbo code parameters like code kind, code-word length, code rate, length of interleaver and delay blocks number of convolution code. The algorithm calculations volume is0.5L3+1.25L, therefore it is suitable for real time systems.
Keywords: Blind Recognition, Turbo Code, Convolution Code, Recursive Systematic Convolution (RSC) Code, Interleaver
