Description: 通过MATLAB软件；通过仿真得出性能曲线；从而比较bpsk的性能-The bit-error rate (BER) of binary phase-shift keying
in Rayleigh fading, using the Alamouti transmission scheme and
receiver selection diversity in the presence of channel-estimation
error, is studied. Closed-form expressions for the BER of log-likelihood
ratio selection, signal-to-noise ratio (SNR) selection, switchand-
stay combining selection, and maximum ratio combining are
derived in terms of the SNR and the cross-correlation coefficient
of the channel gain and its corrupted estimate. Two new selection
schemes, space–time sum-of-squares combining selection diversity
and space–time sum-of-magnitudes selection diversity, are
proposed and proven to provide almost the same performance as
SNR selection, but with much simpler implementations. The effects

Description: The Phase Gradient Autofocus (PGA) algorithm
has been widely used in Spotlight Synthetic Aperture
Radar (SAR) to remove motion-induced blurs in the
images. The PGA algorithm has been proven to be a superior
autofocus method. PGA assumes a narrow beam,
which is valid for most SAR systems. However, lower altitude
SA& have large range dependencies that cannot be
ignored. A new phase estimator for PGA is introduced
and extended to allow range dependence. An ERS-1 image
of Death Valley is used in simulations comparing the
new estimator to the widely used maximum likelihood approach
and in demonstrating the range-dependent PGA
algorithm. Platform: |

结构存在但尚未检测到。通过比较这些结果与最近的分析最大的
可能性的方法,我们能够表明,光谱模块化最大化是一个最佳的检测
方法在某种意义上,没有其他方法会成功的政权失败的模块化方法-We study networks that display community structure—groups of nodes within which connections are
unusually dense. Using methods from random matrix theory, we calculate the spectra of such networks in
the limit of large size, and hence demonstrate the presence of a phase transition in matrix methods for
community detection, such as the popular modularity maximization method. The transition separates a
regime in which such methods successfully detect the community structure from one in which the
structure is present but is not detected. By comparing these results with recent analyses of maximum-
likelihood methods, we are able to show that spectral modularity maximization is an optimal detection
method in the sense that no other method will succeed in the regime where the modularity method fails. Platform: |
