SUMMARY An iterative algorithm is described, based on the replication process of the Hilbert matrix, for encoding and decoding the Hilbert order. The time complexity of the proposed algorithm is smaller than those published previously, and the space complexity is bounded by a constant. Moreover, the new algorithm has a wider applicability when compared with(More)
—This paper proposes an improved decision based feedback scheme for Single carrier transmission with frequency domain equalisation (SC-FDE) communication systems. The approach exploits a processed version of the decisions made in symbol estimation such that the optimisation problem of the equalisation parameters in the frequency domain and the time domain(More)
Introduction Channel equalisation for OFDM signals is an important aspect for achieving good communication performance. Several OFDM based standards, like the European standard DVB-T and the Japanese standard ISDB-T, have adopted the approach of inserting scattered pilots in each transmitted OFDM symbols for some of the modulation modes. Since the data(More)
