  • Massive multiple-input multiple-output (m-MIMO) is used to improve the robustness of data transmission and high sum spectral efficiency in 5G systems. For 5G New Radio (NR) systems need to be designed to reduce cost and complexity, most notably hybrid analog-digital beamforming with large-scale antenna array which has become a major research target.

  • Research works have proposed 1-bit ADC as a good candidate for LS-MIMO systems in order to save both transmission power and circuit energy dissipation. However, we observed that previously reported P-LDPC codes might not have good performance for LS-MIMO systems with 1-bit ADC. Hence, we perform a re-design of the P-LDPC codes for the above systems in this paper. The new codes demonstrate a good coding gain from 0.3 dB at rate 1/2 to 0.5 dB at rate 2/3 in different LS-MIMO configurations with 1-bit ADC.

  • This paper considers a mmWave system where the base station employs a hybrid analog-digital beamforming based on a subarray architecture. Based on a realistic circuit power consumption model that takes into account different signal processing steps at the transmitter, we analyze the energy efficiency (EE) of the system, which is defined as the ratio of the sum achievable rate over the total power consumption.

  • Hybrid analog and digital beamforming (HBF) has recently emerged as an attractive technique for millimeter-wave (mmWave) communication systems. It well balances the deman d for sufficient beamforming gains to overcome the propagatio n loss and the desire to reduce the hardware cost and power consumption. In this paper, the mean square error (MSE) is chosen as the performance metric to characterize the transmission reliability. Using the minimum sum-MSE criterion, we investigate the HBF design for broadband mmWave transmissions.

  • Multi-cell wireless systems usually suffer both intracell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) techniques. Previous works on multi-cell analysis for the microwave band generally consider fully digital beamforming that requires a complete radio-frequency chain behind each antenna, which is less practical for millimeterwave (mmWave) systems where large amounts of antennas are necessary to provide sufficient beamforming gain and to enable transmission and reception of multiple data streams per user.

  • Coldwater disease (CWD) is a bacterial disease that affects a broad host-species range of fishes that inhabit cold, fresh waters. This disease occurs predominately at water temperatures of 16 C and below, and is most prevalent and severe at 10 C and below. Coldwater disease occurs in cultured and free-ranging populations, with hatchery-reared young trout and salmon species especially vulnerable to infections. Flavobacterium psychrophilum is the etiological agent of CWD.
