In recent years, with the continuous development of artificial intelligence technology, application deep counterfeiting technology has become a new trend social networks, bringing vitality in film and television industry, culture education, advertising marketing other fields. Meanwhile, abuse evil use this also aroused widespread concern society. Based on basic principle forgery paper points out that characteristics high degree, rapid iterative optimization, difficult detection...
This paper proposes a design for high-order circular quadrature amplitude modulation (QAM) constellation using partial low-density parity-check (LDPC) coding associated with parallel double Gray mapping aiming at the application to microwave radio backhaul deal time-varying phase noise channels. In proposed QAM design, we first best in which same number of signal points is mapped all concentric rings. Then, decrease inner rings and remap newly added outside original while maintaining high...

In multiple-input multiple-output (MIMO) systems, it is well known that the lattice reduction (LR) can improve performance significantly. LR aided (LRA) linear detectors achieve full diversity with limit complexity. On other hand, Automatic-repeat-request (ARQ) another helpful tool for improving system's reliability, especially when packet data services play a more and important role in wireless communication now. this paper, we propose new receiver MIMO systems ARQ. Based on temporal...
Recently, we proposed a high-order circular quadrature amplitude modulation (QAM) constellation scheme with high low-density parity-check (LDPC) coding rate that is suitable for partial LDPC associated parallel double Gray mapping microwave mobile backhaul.

Computer simulation results show...
This paper presents the bit error rate (BER) performance of frequency domain equalization (FDE) using cyclic-shifted code division multiplexing (CDM) pilot signals for single-carrier line-of- sight (LOS) - multiple-input multiple-output (MIMO) multiplexing. We use different cyclic-shift resources same Zadoff-Chu sequence transmission-stream-specific that are essential estimating channel response FDE and phase noise in LOS-MIMO. Computer simulation results show required received...

Traditionally, a to support single information stream aiming achieve point on the fundamental rate versus diversity tradeoff curve, while proposed class of codes has capability transmitting different performed symbols from layers within same codeword. The UEP-STBC, whose belong orthogonal without interference, fit using scalable video...
This paper presents the bit error rate (BER) performance of frequency domain equalization (FDE) using low-density parity-check (LDPC) coding for single-carrier line-of-sight (LOS)-multiple-input multiple-output (MIMO) multiplexing. We use partial LDPC with double Gray mapping and collaborative decoding, which is suitable a high such as 0.9. Computer simulation results show that decreases required received signal-to-noise power ratio (SNR) at 10 <sup...
This paper presents the bit error rate (BER) performance of frequency domain equalization (FDE) using cyclic-shifted code division multiplexing (CDM) pilot signals for single-carrier line-of-sight (LOS) - multiple-input multiple-output (MIMO) multiplexing. We propose applying different cyclic-shift resources same Zadoff-Chu sequence to transmission-stream-specific that are essential estimating channel response FDE and phase noise in LOS-MIMO. To validate effectiveness multiplexing, we use...
This paper proposes an improved joint detection (JD) approach based on lattice reduction (LR) to promote the link performance of TD-SCDMA system. The LR aided JD transforms system matrix a better conditioned with favorite mathematical properties so as obtain diversity gain. Furthermore, in order reduce complexity LR, is processed through column permutation achieve simple cyclically shifted block matrix. simulation results reveal that has 2.6 dB and 3.5 gain compared traditional at BER=10-5...
The single-carrier frequency division multiple access (SC-FDMA) is employed in the 3GPP Long Term Evolution (LTE) and LTE-Advanced as uplink scheme. In this paper, we propose a novel lattice reduction aided (LRA) detector domain for multiple-input multiple-output (MIMO) SC-FDMA system, which can achieve more diversity than traditional linear frequency-domain equalizer. On other hand, computation complexity be reduced by decreasing dimension of matrix executing LR operation exploring...
