Time-SeriesModelforWirelessFadingChannelsinisotrop
这篇文章为随即和非随机的散射环境中造成的信封衰落提供了一个AR模型。它展示了至少需要一个二阶AR过程去建立一个伏在接收信封内在的阻尼正弦自动/交叉相关函数的模型。通过对模拟值的比较得到使用模型可以得到与理论值近似的值。模型基于的仿真过程被用来与JACK仿真器在随机分散事件中作比较。(his work presents an autoregressive (AR) model
for fading envelope influenced by isotropic and non-isotropic
scattering environments. It is shown that at least a second order
AR process is required to model the damped sinusoidal auto/cross
correlation function inherent in the complex received envelope.
The comparison of statistics of the simulation trace obtained
using the model shows good agreemeqt with the theoretical
values. The model based simulation procedure is compared to
the Jake s simulator for isotropic scattering case and is shown
to exhibit an order of magnitude smaller time complexity. )

OFDM is one of the best physical-layer candidates
for cognitive radio (CR) systems, but rectangular pulse shaping
gives rise to large spectrum sidelobes and interferes with the
licensed user on the adjacent band. In this paper, an approach
is derived based on the signal continuity to measure the spectral
decay rate of the shaping pulse for OFDM.

109201289dg-placement
This paper presents a new method to solve the network reconfiguration problem in the presence of distributed generation (DG) with an objective of minimizing real power loss and improving voltage profile in distribution system. A meta heuristic Harmony Search Algorithm (HSA) is used to simultaneously reconfigure and identify the optimal locations for installation of DG units in a distribution network. Sensitivity analysis is used to identify optimal locations for installation of DG units. Different scenarios of DG placement and reconfiguration of network are considered to study the performance of the proposed method. The constraints of voltage and branch current carrying capacity are included in the uation of the objective function. The method has been tested on 33-bus and 69-bus radial distribution systems at three different load levels to demonstrate the performance and effectiveness of the proposed method. The results obtained are encouraging. (2014-11-17
