This paper presents a new interleaving scheme for efficient data transmission with Orthogonal Frequency Division Multiplexing (OFDM) over fading channels. This approach is based on the chaotic Baker map. The binary data is interleaved with the proposed approach prior to the modulation step. In addition to improve the system performance in fading channel,(More)
Technical impossibility to solve exactly NP-hard combinatorial optimization problems for large instances requires the use of heuristics. Nevertheless, the exact methods can be useful, when sub-problems can be extracted from the whole problem. Indeed, their resolution contributes in the global solution search, by combining exact resolution of sub-problems(More)
