چکیده
Absrruct-This paper discussed the spatial 'or angular spreading properties of wireless propagation in the urban microcell environment, which is of great interests of future mobile technology, especially in case of using smart antennas. Based on the elliptical scattering model, the power azimuth spectrum in microcell environments is derived and it is found that the result approximately followed a truncated Laplacian distribution. The parameter of the Laplacian function is determined by regression. The results can provide insight into the spatial spreading properties of the wireless channel and can be used easily for further research.

Azimuth-Power-Spectrum Prediction by Site-Specific Stochastic Channel Modeling in a Microcell Line-of-Sight Scenario
A channel model for line-of-sight (LoS) microcell in dense urban areas is proposed. It is a kind of geometry-based stochastic channel model (GSCM) for which the scattering-powerdistribution (SPD) in the channel seen from the receiver mobile terminal (MT) based on the physical phenomenon is obtained. Furthermore, information from a specific environment can be inserted into the model to acquire t...

A stochastic channel model for line-of-sight (LoS) street microcell scenarios in dense urban areas is proposed. The scattering power distribution (SPD) in the channel seen from the mobile terminal (MT) based on the physical phenomenon is obtained. The coefficients of the distribution are derived by approximation to the measurements performed in urban street microcell scenarios. The azimuth-powe...

In wireless channel the noise has a zero mean. This channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. The averaging process will reduce the effect of the noise in the decision variable that will approa...
