PURPOSE The aim of this paper is to understand the sustainability of urban spatial transformation in the process of rapid urbanization, and calls for future research on the demographic and economic dimensions of climate change. Shanghai towards its transformation to a metropolis has experienced vast socioeconomic and ecological change and calls for future(More)
In this paper, we analyze the performance of the channel estimation methods (LS, LMMSE, ALMMSE) for MBSFN in LTE system. Two methods, with and without linear interpolation, are proposed for extracting the special designed pilot in MBSFN frame. The linear interpolation method is more accurate and complicated while the non-interpolation method, with about(More)
Co-Channel Dual Polarization (CCDP) technology is an efficient way to double the link capacity in modern communication system. However, the consequent polarization interferences become an inevitable problem to fight. Therefore, a Cross-Polarization Interference Canceller (XPIC) is necessary against the cross-talks. This paper focuses on the baseband XPIC(More)
Limited feedback of channel state information (CSI), which is made up of rank indicator (RI), precoding matrix indicator (PMI) and channel quality indicator (CQI), is an important part in closed-loop transmission for 3GPP Long Time Evolution (LTE)/LTE-Advanced standard. In this paper, an efficient way, where PMI granularity selection method is used in PMI(More)
Aimed at the problem of the near-field imaging in real time, a near-field narrow 2-D imaging algorithm based on the combination of single-input multiple output array (SIMO) and synthetic aperture radar (SAR) is proposed. By combining a real aperture and synthetic aperture, a 2-D synthetic aperture plane which is in terms of spatial sampling to obtain the(More)
Blind equalizer has always been a hot issue that causes a great deal of research in modern digital communication system. Constant modulus algorithm (CMA) is a most popular one for the simple and effective. However, CMA algorithm has faster convergence rate but weak tracking performance in steady-state, especially in high-order QAM system. In this paper, a(More)
