We propose a novel method for joint two-dimensional (2D) direction-of-arrival (DOA) and channel estimation with data detection for uniform rectangular arrays (URAs) for the massive multiple-input multiple-output (MIMO) systems. The conventional DOA estimation algorithms usually assume that the channel impulse responses are known exactly. However, the large number of antennas in a massive MIMO system can lead to a challenge in estimating accurate corresponding channel impulse responses. In contrast, a joint DOA and channel estimation scheme is proposed, which first estimates the channel impulse responses for the links between the transmitters and antenna elements using training sequences. After that, the DOAs of the waves are estimated based on a unitary ESPRIT algorithm using previous channel impulse response estimates instead of accurate channel impulse responses and then, the enhanced channel impulse response estimates can be obtained. The proposed estimator enjoys closedform expressions, and thus it bypasses the search and pairing processes. In addition, a low-complexity approach toward data detection is presented by reducing the dimension of the inversion matrix in massive MIMO *** cases for the proposed method are analyzed by changing the number of antennas. Experimental results demonstrate the validity of the proposed method.

Rare Metals 2014年第2期33卷 111-126页

作者： kuang-Di Xu Zhong-ming Ren Chuan-Jun Li Laboratory of Modern Metallurgy and Material Processing Shanghai University

Rare metals play an important role in development of superalloys. Over the last two decades, the application of the rare metals in superalloys has achieved progress significantly. They present multi-beneficial effects for strengthening the matrix and the cophase, increasing the lattice misfit, cleaning the grain boundary, improving the carbides and eutectics, refining the grain, stabilizing the oxidation film, etc., so that the elevated temperature rupture life and elevated temperature oxidation resistance are improved significantly, leading to a broad application in the superalloys. In order to meet the higher demand for better superalloys in the future, more intensive research is necessary on the effects of the rare metals on the superalloy, and especially on the combination effect of various rare metals and mutual influence among them. Utilization of the computational materials science and combinatorial high throughput experiment will be of importance in application of rare metals in superalloys.

以商用2195-T6铝锂合金板材为研究对象,借助单向拉伸试验,获得了其真应力-真应变曲线;以此为基础,建立了能够表征2195铝锂合金变形损伤的GTN模型和反复弯曲成形的数值仿真模型,对反复弯曲成形过程中弯曲次数和压下量对板材的回弹和损伤特征的影响进行分析,并通过试验验证了反复弯曲对回弹的影响。结果表明:在单次弯曲变形中,随着弯曲压下量的增加,塑性弯曲变形区逐渐增大;当压下量大于临界值时,随着压下量的增加,回弹量逐渐减小。在相同的压下量条件下,随着弯曲次数增加,板材的塑性变形区逐渐增加,回弹量逐渐减小;但是随着弯曲次数的增加,板材的损伤逐渐增大,因此,通过反复弯曲成形抑制弯曲回弹需要将板材的内部损伤控制在许可范围内。

In this paper, we propose a novel approach to enhance the performance of frameless slotted ALOHA(SA) protocol. We employ signature codes to help the receiver identify the packets contained in collisions, and use successive interference cancellation(SIC) for packet recovery. We model the proposed scheme as a two-state Markov model represented by a uni-partite graph. We evaluate the throughput,expected delay and average memory size of the proposed scheme, and optimize the proposed scheme to maximize the throughput. We show that the theoretical analysis matches well with simulation *** throughput and expected delay of the proposed protocol outperform the conventional slotted ALOHA protocol significantly.

We present a scheme for probabilistic remote preparation of multi-qubit with three-party from a sender to either of two receivers. The quantum channel is composed of a partial entangled tripartite GHZ state. We obtain the successful totM probability of the scheme in the general case and special case, respectively. We also calculate total classical communication cost required in the RSP process with three-party in the general case and special case, respectively.
