We used TCA approaches, such as the validity claims that should characterize argumentative debate and the interactive processes with ‘lifeworld'components(culture, person and society), to create a theoretical relationship between Habermas' s theory and SP practices. We propose that the TCA aligns with the objectives of a dialogic communication about science with the non-specialist public and can contribute to perspectives that emphasize dialogue about science in society. We conclude that the premises of communicative action can guide SP policies.展开更多

The analytic relationship between the powers and the correlation matrix of multipath components established the feasibility of the application of the MDL criterion to RDS estimation. The estimator presented both the estimate of instantaneous RDS and the estimates of noise variance, channel power and SNR of current channel with low computational complexity. Given the powers of the estimated multipath components, the MDL criterion was adopted to acquire the number of paths and the time delays of each path of current channel without making eigendecomposition of the correlation matrix normally required by MDL criterion, following which the noise variance and the power of each path can be estimated. The power delay profile (PDP) and RDS of the current channel were achieved. Simulation results showed that the proposed estimator was insensitive to variance of SNR and robust against frequency-selectivity.展开更多

Three aspects including space, time domain and frequency domain are united for the research on the distribution of frequency spectrum. The simulation result shows that, in the space domain, time domain, frequency domain algorithm, the transmitted data volume and the total throughput of the system are superior to those in greedy algorithm and time domain—frequency domain algorithm, the novel algorithm is helpful to reduce the disturbance caused by a cognitive user to an authorizing user and lower the competition between cognitive users, this simulation result shows that the proposed algorithm is effective.展开更多

First we introduce a Lie group structure and a Riemannian structure on the manifolds of the FIR filters. Then we derive the natural gradients on the manifolds using the isometry of the Riemannian metric. Using the natural gradient, we present a novel learning algorithm for blind deconvolution based on the minimization of mutual information. Some properties of the learning algorithm, such as equivariance and stability are also studied. Finally, the simulations are given to illustrate the effectiveness and validity of the proposed algorithm.展开更多

Based on the combination of Alamouti space-time code and time hopping ultra-wide band （TH-UWB） communications, a novel repetition space-time coding （RSTC） method for mobile 2x2 free-space optical communications with pulse position modulation （PPM） is devel- oped. In particular, two decoding methods of equal gain combining （EGC） maximum likelihood detection （MLD） and correlation matrix detection （CMD） are derived. When a quasi-static fading and weak turbulence channel model are considered, simulation results show that whether the channel state information （CSI） is known or not, the coding sys- tem demonstrates more significant performance of the symbol error rate （SER） than the uncoding. In other words, transmitting diversity can be achieved while conveying the information only through the time delays of the modulated signals transmitted from different antennas. CMD has almost the same effect of signal combining with maximal ratio combining （MRC）. However, when the channel correlation increases, SER performance of the coding 2×2 system de- grades significantly.展开更多

American Christianity, however, is imbued in a modem---even pre-modern--paradigm. As a result, many contemporary religious leaders find it difficult to communicate with their postmodern constituents, as evidenced by declining attendance rates and religious affiliation. The present study explores this dilemma by offering potential implications for contemporary religious leaders to communicate more effectively with emerging/emergent generation（s）. The author begins this exploration, first, by outlining the philosophical tenants of postmodemism： its epistemological, ontological, and axiological assumptions. Second, the author delineates several key characteristics of postmodern religious communication. Next, the author offers three practical implications for organizational leaders： （1） increased use of personal narrative, （2） removal of hierarchal boundary structures, and （3） increased awareness and appreciation for divergent perspectives. The author concludes this study with directions for future research.展开更多
