We introduce an efficient soft-decision decoder for permutation block codes when assuming AWGN and slow fading frequency-nonselective channels. The decoder implements a combination of the Hungarian algorithm and Murty’s algorithm for the $k$ th assignment. Results show that the proposed algorithm achieves better coding gain when compared with hard-decision decoding. A salient feature of the decoder...
A novel solution of the inverse Frobenius-Perron problem for constructing semi-Markov chaotic maps with prescribed statistical properties is presented. The proposed solution uses recursive Markov state disaggregation to construct an ergodic map with a piecewise constant invariant density function that approximates an arbitrary probability distribution over a compact interval. The solution is novel...
