This paper focuses on the study of low density parity check (LDPC) coded multiple-input multiple-output (MIMO) systems for high throughput wireless communication. The evaluation and implementation of quasi-cyclic LDPC (QC- LDPC) code in MIMO-OFDM systems are presented. QC-LDPC has comparative error correcting performance with random LDPC and considerably(More)
The receptor activator of nuclear factor κ-B ligand (RANKL)/RANK pathway plays an important role in breast cancer progression. Despite the known role of Casitas B-lineage lymphoma (Cbl)-b as an essential regulator of the RANKL/RANK pathway, its effect on RANK pathway in breast cancer remains unclear. Thus, the present study investigated the effect of Cbl-b(More)
In this paper, the evaluation and the implementation of quasi-cyclic LDPC (QC-LDPC) codes in MIMO-OFDM systems are presented. QC-LDPC has comparative error correcting performance with random irregular LDPC and considerably reduces complexity. We evaluate communication performance of the QC-LDPC coded system based on the IEEE802.11n standard in a 4 times 4(More)
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)
—The multiple-input multiple-output (MIMO) technique can greatly improve coverage and throughput in wireless networks. However, varying channel parameters create unfavorable conditions that make the transmission less reliable. Unfortunately, many previous MIMO evaluations suffer from limited practical relevance due overly-simplified assumption about the(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)
BACKGROUND Lung cancer is a common malignant tumor. The aim of this study is to assess the short-term effect of video-assisted thoracoscopic surgery lobectomy and thoracotomy lobectomy in the treatment of non-small cell lung cancer. METHODS Cochrane Library, Embase, Pubmed, CBM, CNKI, VIP, and so on, were searched by computer. Randomized controlled trials(More)
