This paper explores and compares different dynamic subcarrier allocation (SA) schemes for single carrier (SC) FDMA systems. A so-called maximum greedy algorithm is proposed, which outperforms the existing greedy algorithm. We also provide an optimum solution for SA by using the so-called Hungarian algorithm. Furthermore, all the algorithms presented in this paper are very general and can be extended...
We propose a novel blind equalization structure based on independent component analysis (ICA) for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. A linear precoding is exploited to resolve completely the phase and permutation ambiguity of the ICA model, by using the correlation between the source data and the reference data. Furthermore, iterative channel...
