Orthogonal frequency division multiplexing with index modulation (OFDM-IM) is a newly proposed technique, which achieves significantly improved performance in comparison with classical OFDM by using the indices of active subcarriers to carry additional information bits. In this paper, we propose two power allocation (PA) algorithms for the sake of further improving the bit error rate (BER) performance...
Orthogonal frequency division multiplexing with index modulation (OFDM-IM), which uses the indices of activated subcarriers to carry additional information bits, is a novel multicarrier transmission technique. In this paper, a profile-based power management relying on maximal minimum Euclidean distance (MED) criterion is proposed. Moreover, a low-complexity subset searching method based on the normalized...
Multiple-input multiple-output (MIMO) single carrier frequency division multiple access (SC-FDMA), which combines the advantage of spatial and frequency diversities with frequency domain equalizers (FDE), has drawn great attention recently. Among all possible detection techniques, maximum-likelihood detection (MLD) is optimal, but its exponentially computational complexity precludes its use in practical...
H.264/AVC the latest international video coding standard achieves higher compression efficiency than previous video coding standards such as MPEG-4 and H.263. However, this performance gain comes at the cost of an increased computational complexity. To achieve a high coding efficiency, H.264/AVC employs complex mode decision techniques based on Rate Distortion Optimization, the computational complexity...
