Successive Interference Cancellation for DS-CDMA Systems with Transmit Diversity

open access: yesEURASIP Journal on Wireless Communications and Networking, 2004
We introduce a new successive interference cancellation (SIC) technique for direct sequence code division multiple access (DS-CDMA) systems with transmit diversity. The transmit diversity is achieved with a space-time block code (STBC).

Analysis of transmit-receive diversity in Rayleigh fading [PDF]

open access: yesGLOBECOM'01. IEEE Global Telecommunications Conference (Cat. No.01CH37270), 2002
We analyze the error performance of a wireless communication system employing transmit-receive diversity in Rayleigh fading. By focusing on the complex Gaussian statistics of the independent and identically distributed entries of the channel matrix, we derive a formula for the characteristic function (c.f.) of the maximum output signal-to-noise ratio ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

ce-time coded scheme for two-way relay system

open access: yesTongxin xuebao, 2015
In two-way relay system,focusing on the problem that using SSK transmission can not achieve the transmit diversity and has lower spectral efficiency,a diagonal space-time coded spatial modulation scheme called DSTC-SM scheme was proposed.In the DSTC-SM ...

Differential spatial modulation scheme based on orthogonal space-time block coded

open access: yesTongxin xuebao, 2017
Focusing on the problem that differential spatial modulation (DSM) couldn’t obtain transmit diversity and has high decoding complexity,a new differential spatial modulation scheme based on the orthogonal space-time block code was proposed and the ...

Transmit Diversity in the Downlink for the TETRA-TEDS System

open access: yesJournal of Telecommunications and Information Technology, 2014
In the paper a proposal for the improvement of performance for the TETRA Enhanced Data System (TEDS) employing transmit diversity based on two antennas in the downlink is described.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Jointly optimal transmit and receive diversity

open access: yesElectronics Letters, 2002
The effects of fading in mobile radio channels can be mitigated using space diversity techniques. One diversity scheme which is applicable to multiple transmit and receive antennas is maximum ratio transmission (MRT). Here, it is shown that a certain constraint on the MRT receiver combining weights results in performance degradation. A new transmit and

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Transmit Diversity-Achieving Quadrature Index Modulation Aided Media-Based Modulation

open access: yesIEEE Access
In this paper, a new schematic of quadrature index modulation (QIM) with generalized spatial constellations is proposed and amalgamated with the media-based modulation (MBM) system for not only achieving the transmit diversity gains but also increasing ...
