Blind Recognition

A novel algorithm of blind recognition of Bose-Chaudhuri-Hocquenghem (BCH) codes is proposed to solve the problem of Adaptive Coding and Modulation (ACM) in cognitive radio systems. The recognition algorithm is based on soft decision situations. The code length is firstly estimated by comparing the Log-Likelihood Ratios (LLRs) of the syndromes, which are obtained according to the minimum binary parity check matrixes of different primitive polynomials. After that, by comparing the LLRs of different minimum polynomials, the code roots and generator polynomial are reconstructed. When comparing with some previous approaches, our algorithm yields better performance even on very low Signal-Noise-Ratios (SNRs) with lower calculation complexity. Simulation results show the efficiency of the proposed algorithm.

Blind Recognition

As to the problem of blind recognition for convolutional code, the existing recognitory methods’ principle and process are summarized, and they are simulated and analyzed with Matlab. Four methods are introduced for the recognition of generation polynomials, and the comparison of these methods shows that the Euclidean algorithm works better at low BER, while the method based Walsh-Hadamard transform has a better accuracy when BER is as high as 10-2.
