Study on power azimuth spectrum of wireless channel in microcell environments
Ao Tang, Gong Ke · 2004
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.
