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)
Wireless OFDM signals typically have a cyclic-prefixed guard interval. The FFT timing synchronisation at the receiver is traditionally based on the peak point of the correlation output between the guard interval and its corresponding duplicate at the OFDM symbol's tail. This approach does not in general find the optimum timing position for the FFT when the(More)
