Smart antenna systems have been proposed and demonstrated at both the transmitter and receiver of wireless communication systems, so that the quality of service improves at both ends. We propose multiple-input multiple-output (MIMO) beamforming for frequency-selective fading channels to maximize the signal-to-noise-and-interference ratio (SINR) based on an(More)
In this paper, we propose a multiple-input multipleoutput (MIMO) beamforming scheme for a multiuser system in frequencyselective fading channels. The maximum signal-to-noise and interference ratio (MSINR) is adopted as a criterion to determine the transmit and receive weight vectors. In order to maximize the output SINR over all users, two algorithms for(More)
We propose a simple method of designing MIMO communication systems using a TDL structure in the receiver side. Based on a maximum SINR (signal-to-interference-and-noise ratio) criterion, weight vectors in both the transmitter and receiver arrays are determined alternately, fixing one side while calculating the other, and this operation is repeated until the(More)
Nowadays, MIMO systems are playing an important role in wireless communications. In this paper, we propose a spatial-temporal adaptive MIMO beamforming scheme for single carrier transmission in frequency-selective fading channels with the assumption of perfect channel state information (CSI) at both the transmitter and receiver. The transmit and receive(More)
In this paper, we propose a spatial-temporal adaptive MIMO beamforming scheme for single carrier transmission in frequency-selective fading channels with an assumption of perfect channel state information (CSI) at both transmitter and receiver sides. The transmit and receive weight vectors are estimated by using an iterative update algorithm to detect the(More)
In recent years, multiple-input multiple-output (MIMO) antennas systems have quickly become an inevitable wireless technology not only for WLANs but also for mobile networks. Based on the benefits of using multiple transmit antennas and multiple receive antennas, MIMO systems can provide high quality and high speed services. However, for high speed(More)
Nowadays, lung diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis, are increasingly attracting the attention of the world medical community. The main reason is due to the increasing environmental pollution problem. Therefore, detecting pulmonary exacerbations and improving outcomes of chronic lung ailments are in(More)
