Blind Recognition of BCH Product Codes

As a result of growing application of concatenated codes such as product codes in military wireless communication systems, the ability of blind recognition and reconstruction of such codes in electronic warfare (EW) systems is one of the important necessities. So far, diverse methods for recognition of forward error correction (FEC) codes have been suggested; however, in terms of blind recognition of TPCs no method has been introduced yet. In this paper, we have tried to generalize the existing methods for recognition of two-dimensional TPCs. We apply two well-known methods of blind recognition, i.e. greatest common divisor (GCD) and matrix rank (MR), for recognition of these codes. Based on these methods, code parameters, i.e. code word length, message length, and the structure of code are determined. Simulation results are presented and analyzed which prove the effectiveness of the proposed method.
