Power allocation is one of the key technologies in wireless communication system. The research on how to improve system performances via power allocation is important for cooperative communication system. In this paper, firstly, we analyze a multi-node cooperative communication system, then the paper aims at proposing a power allocation scheme. Through analysis and simulation study, the proposed scheme is able to improve system capacity and reduce outage probability compared to the traditional power allocation scheme. At last, system performances with different relay positions are compared.

To get a thorough understanding of the properties and regulations of space tracking ship's swaying data errors so as to effectively eliminate their influences on measurement data, a nonlinear auto-regressive moving average model with exogenous inputs (NARMAX) has been developed by applying modern theories and the latest technologies. The process model of NARMAX was determined by orthogonal regressive method and the algorithm to determine noise model was also designed. After evaluating its fitting errors by comparing them with those of linear ARMA models, also by performing statistics and test for the redundant residuals, we can draw such conclusions as: The proposed NARMAX model can better fit ship swaying data errors, whose covariance and mean values prove to be much smaller than those processed by linear ARMA models, also it is more stationary and accurate, all of which validate that NARMAX can give a better description of the complicated characteristics and objective regulations of ship swaying data errors.

In various electronic systems or equipment, phase noise has important research value as an important indicator existing and seriously affecting its performance. Thus it is significance to propose a correct and efficient simulation method for generating phase noise. In this paper, an effective and practical simulation method is put forward to generate the phase noise of oscillators built on the work and insight of predecessors. This novel method is described in detail and focuses on the generation processes of phase noise. In the novel method, FIR shaping filters are used to generate power-law noise components which are further processed to obtain the phase noise data consistent with specified noise coefficients in time domain, and the method is also validated in the frequency domain. All in all, the paper provides a theoretical basis and implementation method for the study of short-term frequency stability of frequency sources.

In this note, we discuss the properties of model predictive control of nonlinear systems with input constraints. It shows that the prediction trajectory will not leave the terminal set once it enters into it, and the terminal state lies in a sublevel set of the terminal set if there exists a point of the prediction trajectory lying in the sublevel set. Furthermore, we show that the feasible set of the related optimization problem is a bounded set around the origin.

Vertical organic photoelectric transistors (OPTs) with copper phthalocyanine (CuPc) as active layers have been fabricated. The structure of OPTs fabricated consists of five layers of Cu/CuPc/Al/CuPc/ indium tin oxide (ITO). Compared with traditional organic field effect transistor (OFETs), the structure of vertical conductive channel in OPTs is advanced to static characteristics with high working current value, low operation voltage and large switching current ratio. The static current-voltage output characteristics of OPTs in 700 nm light and in dark are observed. It can be seen that emitter-collector current (Iec) increases steadily with the increase of emitter-collector voltage (Vec). But Iec decreases with the increase o f base voltage (Vb), and that is the increase of Schottky barrier in base region. The operation current in 700 nm light is larger than the one in dark. The switching current ratio is 14.5.
