241. The fading time of the ACB sample under different radiation intendity can be predicted with the kinetic equations reported. 242. In error-rate expression the effects of Rayleigh fading, frequency-and time-selective fading on HF ionospheric channels, quadruple frequency diversity and white noise have been considered. 243. Fei Ming, who came into the literary world with the fading of the 4th, May Literature, is the pathbreaker of pastoral fiction. 244. Interchannel interference(ICI) is a dominant source of error for OFDM systems in mobile dispersive fading channels. This paper provides an ICI analysis in time-variant multipath channels. 245. This paper presents a baseband discrete-time state-space model for generation of Rayleigh MD(multiplicative distortion) in a frequency flat fading channel. 246. We studied the performances of this system by simulations, including the impacts of channel fading, angle spread and co-channel interference on DOA estimation. 247. At the beginning of this paper, a distributed MIMO channel model taking path loss, shadow fading and small scale fading into account is established. 248. The feature used in the algorithm is invariant with respect to flat fading, and can resist multipath fading of frequency-selecting channel in quite a few degree. 249. This paper applies wavelet and fractal theories to analyze multipath fading signal in mobile radio communications for the first time. 250. The article discusses the performance of adaptive algorithm applying in smart antenna in wireless fading channel. 251. The combination of MIMO and OFDM greatly increases the system capacity in the sense that OFDM and MIMO can respectively provide flat fading channel and spatial gain. 252. The fading statistics is achieved by in-phase and quadrature modulation at the radio signal by two independent Gaussian noise signals. 253. Deduce the error probability formulation of noncoherent unitary code under spatial fading correlation. 254. Now, they struggle to keep their own way of life, language and identity from fading away. 255. For safety reasons the "quiet" time must be at least 65 seconds longer than the fading time, it must also be more than 10 seconds. 256. Many men still rise when ladies enter the room on a social occasion—although the custom is fading with the younger generation and under the impact of Women's Lib. 257. To let a moment expand into a never - fading memory, better to live fully in that moment. 258. Typical examples of modeling flat fading channels in MATLAB were simulated specifically by means of user-defined m-files. 259. A new transmission scheme, which combines transmit preprocessing with multiuser MIMO downlink system over frequency-selective fading channel is proposed. 260. This paper studied a new space-time-frequency coding for orthogonal frequency-division multiplexing (STFC-OFDM) transmissions over frequency-selective Rayleigh fading channels. 261. Orthogonal frequency division multiplexing ( OFDM ) is a bandwidth - efficient modulation scheme with robustness to frequency selective fading. 262. The statistic model of air-ground radio communication channel is characterized by the multipath fading,[www.] Doppler power spectrum and delay power spectrum. 263.
