Reconstruction of a Non-binary Block Code from an Intercepted Sequence with Application to Reed-Solomon Codes

Parameter Identification of Reed-Solomon Codes over Noisy Environment

“…In Fig. 2, the variation of ρ (m, p, φ) is shown for all possible combinations of [m, p, φ], where m ∈ [4,6], assuming RS(63, 45, 6, 67), 64-QAM scheme (i.e. M = 64 and M 1 = 6), ∆ = 6, t = 1, and non-erroneous scenario.…”

“…• Simulation results are given for different test cases validating the proposed algorithms. • The performance of the algorithm in terms of accuracy of estimation is compared with the performance of the Barbier's method proposed for non-binary codes in [4] and the LLR-based technique proposed in [6]. • In order to show the robustness of the proposed algorithm, the accuracy of parameter estimation of RS codes by varying the signal-to-noise ratio (SNR) values is given for different values of M and k.…”

“…Further, the blind recognition of codeword length for different non-binary error correcting codes was extensively investigated over noisy environment in [3]. In [4], the algorithm for blind estimation of RS code parameters was reported by adding symbol errors over RS encoded data without using any modulation schemes. The algorithm was based on Barbier's dual code method developed for binary codes in [5] and the same was generalized in [4] to non-binary codes.…”

The algorithm was based on Barbier's dual code method developed for binary codes in [5] and the same was generalized in [4] to non-binary codes. In [6], [7], and [8], the novel code parameter recognition technique based on the average log-likelihood ratio (LLR) of syndrome a posteriori probability (SPP) was proposed for RS codes, low-density parity-check (LDPC) codes, and convolutional codes, respectively.…”

Parameter Estimation of Turbo Code Encoder

“…Channel code reconstruction problem is usually considered in noncooperative communication scenarios, where finding the structure and parameters of the channel code is a major goal of the receiver [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Since turbo codes are introduced in many standards and applications [15][16][17][18][19][20][21][22], blind reconstruction of turbo codes in practical noncooperative situations is a well motivated problem.…”
