This paper studies zero-forcing (ZF) detection for multiple-input multiple-output (MIMO) wireless communications systems and transmit-correlated and estimated Rician fading with realistic azimuth spread (AS) and A"-factor. Due to the nonzero-mean channel gain matrix, the matrix that determines the symbol-detection signal-to-noise ratio for the(More)
In recent years, there have been significant breakthroughs in wireless communication systems design based on the multiple-input multiple-output (MIMO) concept. Exploiting the channel state information at the transmitter (CSIT) can improve the link performance. Thus, MIMO precoding has been an active research area for wireless communications. By specifying a(More)
For multiple-input/multiple-output (MIMO)-based wireless communications systems with precoding, we evaluate the symbol-detection performance for Rician fading. We first consider, as in conventional evaluation approaches, fixed channel statistics, i.e., typical settings for the azimuth spread (AS), Rician K-factor, and deterministic channel matrix component(More)
Objective: To analyze the normal value of the iodine content in the left ventricular myocardium of healthy subjects and to observe if there is a segmental differences on iodine distribution by using the second generation dual-source dual-energy computed tomography myocardial first perfusion imaging. Methods: In this retrospective study, 42 healthy subjects,(More)
Adopting orthogonal frequency division multiplexing (OFDM) to low-density parity check (LDPC) coded Multiple-input multiple-output (MIMO) is attractive scheme for wireless communication systems. An iterative receiver design for LDPC coded MIMO-OFDM system is proposed as the foundation for enhancing the wireless link performance can deliver the coverage,(More)
In this study, a biological system consisting of an up-flow anaerobic sludge blanket (UASB) and anoxic-oxic (A/O) reactor was established for the advanced treatment of high ammonium urban landfill leachate. The inhibitory effect of free ammonia (FA) and free nitrous acid (FNA) on the nitrifying bacterial activity was used to achieve stable nitritation in(More)
