PURPOSE To present a HOmologous Black-Bright-blood and flexible Interleaved imaging (HOBBI) sequence for dynamic contrast-enhanced magnetic resonance imaging (MRI) of the vessel wall. THEORY AND METHODS A HOBBI sequence is proposed to acquire high-spatial-resolution black-blood and high-temporal-resolution bright-blood dynamic contrast-enhanced images in(More)
This paper presents a new predistortion scheme based on radial basis function (RBF) neural network for high-power amplifier (HPA) with memory in an orthogonal frequency division multiplexing (OFDM) system. An efficient algorithm to update the neural network weights parameters and the centers and widths of RBF is derived. Simulation results show that the(More)
BACKGROUND Most common systems of genetic engineering of mammalian cells are associated with insertional mutagenesis of the modified cells. Insertional mutagenesis is also a popular approach to generate random alterations for gene discovery projects. A better understanding of the interaction of the structural elements within an insertional mutagen and the(More)
The frequency shift of the ultra-narrow frequency shift keying (UNFSK) is far less than the ordinary binary frequency shift keying (FSK) method. Because the two frequencies of UNFSK are extremely close, the traditional demodulation method cannot separate them successfully. This study aims to successfully demodulate the UNFSK signals by applying cycle(More)
A low complexity block soft feedback equalization based on sequence detection is presented for turbo equalization. The proposed algorithm can be used in the channel equalizer for calculation of the a posteriori probability (APP) by collecting information of the entire block as in MAP algorithm. The sequence-based detection is made possible by combining both(More)
—In this paper, we proposed a novel method for constructing quasi-cyclic low-density parity-check (QC LDPC) codes based on cyclic subgroup over GF() q. LDPC codes constructed by this method are quasi-cyclic (QC) and they perform very well over the additive white Gaussian noise (AWGN) with sum product algorithm (SPA). The main advantage is that QC LDPC codes(More)
