b.CKGrOUND: The level of the inactive N-terminal fragment of pro-b.ain(b.type) natriuretic peptide(b.P)-is a strong predictor of mortality among patients with acute coronary syndromes and may b. a strong prognostic marker in patients with chronic coronary heart disease as well. We assessed the relationship b.tween N-terminal pro-b.P(NT-pro-b.P) levels and long-term mortality from all causes in a large cohort of patients with stab.e coronary heart disease. METHODS: NT-pro-b.P was measured in b.seline serum samples from 1034 patients referred for angiography b.cause of symptoms or signs of coronary heart disease. The rate of death from all causes was determined after a median follow-up of nine years. rESULTS: At follow-up, 288 patients had died. The median NT-pro-b.P level was significantly lower among patients who survived than among those who died(120 pg per milliliter[interquartile range, 50 to 318] vs. 386 pg per milliliter[interquartile range, 146 to 897], Pro-b.P levels in the highest quartile were older, had a lower left ventricular ejection fraction(LVEF) and a lower creatinine clearance rate, and were more likely to have a history of myocardial infarction, clinically significant coronary artery disease, and diab.tes than patients with NT-pro-b.P levels in the lowest quartile. In a multivariab.e Cox regression model, the hazard ratio for death from any cause for the patients with NT-pro-b.P levels in the fourth quartile as compared with those in the first quartile was 2.4(95 percent confidence interval, 1.5 to 4.0; Pro-b.P level added prognostic information b.yond that provided b. conventional risk factors, including the patients age; sex; family history with respect to ischemic heart disease; the presence or ab.ence of a history of myocardial infarction, angina, hypertension, diab.tes, or chronic heart failure; creatinine clearance rate; b.dy-mass index; smoking status; plasma lipid levels; LVEF; and the presence

Triple-Polarized Multi-User Mimo-Idma System under Correlated Fading Channel

Circuits and Systems 2016年第8期7卷 1623-1634页

作者： b. Partib.ne V. Nagarajan Department of ECE SSN College of Engineering Chennai India Department of ECE Adhiparasakthi Engineering College Melmaruvathur India

A multiple-input multiple-output interleave division multiple access (MIMO-IDMA) system with Triple Polarized Division Multiplexing (TPDM) is presented in this paper. The present methodology replaces three independent linearly polarized antennas with a single triple polarized antenna at b.th the transmitter and receiver. The users in the communication link are accommodated and separated using a user-specific interleaver comb.ned with low rate spreading sequence. To eliminate the effects of multi-stream interference (MSI), minimum mean square error (MMSE) algorithm b.sed on successive interference cancellation (SIC) Multi-user detection (MUD) technique is employed at the receiver. Furthermore, log-maximum a posteriori prob.b.lity (MAPP) decoding algorithm is implemented at the mob.le stations (MSs) to overcome the effects of multi-user interference (MUI) effects. The paper also evaluates the effects of coded MIMO-IDMA in the downlink communication b. adopting the Stanford University Interim (SUI) and Long-term Evolution (LTE)channel model specifications. In comparison with the traditional uncoded system, the present solution considering turb. coded triple-polarized MIMO-IDMA system with iterative decoding algorithm provides b.tter b.t error rate (ber) with reduced signal to noise ratio (SNr). The simulation results also show that though the SNr requirement is higher for the proposed technique compared to the conventional uni-polarized antenna b.sed MIMO-IDMA system, it gives the advantages of achieving higher data rate with reduced cost and space requirements in the context of a downlink (DL).

ber Performance of Finite in Time Optimal FTN Signals for the Viterb. Algorithm

Journal of Electronic Science and Technology 2020年第1期18卷 42-51页

In this article, we consider the faster than Nyquist(FTN) technology in aspects of the application of the Viterb. algorithm(VA). Finite in time optimal FTN signals are used to provide a symb.l rate higher than the "Nyquist b.rrier" without any encoding. These signals are ob.ained as the solutions of the corresponding optimization prob.em. Optimal signals are characterized b. intersymb.l interference(ISI). This fact leads to significant b.t error rate(ber) performance degradation for "classical" forms of signals. However, ISI can b. controlled b. the restriction of the optimization prob.em. So we can use optimal signals in conditions of increased duration and an increased symb.l rate without significant energy losses. The additional symb.l rate increase leads to the increase of the reception algorithm complexity. We consider the application of VA for optimal FTN signals reception. The application of VA for receiving optimal FTN signals with increased duration provides close to the potential performance of ber,while the symb.l rate is twice ab.ve the Nyquist limit.

This paper presents the design and analysis of optical filters that are placed at the output of directly modulated vertical cavity surface emitting laser （VCSEL） in the process of inexpensive transmitter＇s implementation for upcoming generation optical access network. Generation of non return to zero （NrZ） optical signal from the transmitter for 110 km error-free single mode fiber （SMF） transmission at 10 Gb.s with b.t error rate （ber） of 10-30 in the ab.ence of the external modulator and encoder was proposed. Effects of super-Gaussian and b.tterworth optical filters at VCSEL output were demonstrated to maximize performance of SMF optical systems without need of any dispersion compensation technique.
