摘要
In this letter, probability density functions (pdf's) describing various physical aspects of hybrid cellular code-division multiple-access/space-division multiple-access (CDMA/SDMA) networks are derived. All mobile users are considered to be surrounded by a Gaussian bell shape of scattering elements, and a general rule of thumb for the standard deviation of the scattering elements is proposed. Second, in order to describe the distribution of mobile users in the cell, a general pdf describing mobile user distributions is proposed. Using the mentioned distribution a general pdf for the angle-of-arrival (AOA) of signals at the CDMA base station is derived.
