A generalized model of superposition of radio signals in a given frequency sub-band on the antenna array of arbitrary geometry
Miljko Eriæ
A generalized spatial mathematical model of superposition of multiple incident radio signals in a given frequency sub-band on the antenna array of arbitrary volume non-uniform geometry is presented in this paper. All parameters of the model are normalized so that this model could be applied without restrictions to the modeling of signal superposition in different frequency ranges, as well as to the modeling of multi-user signal scenario with different multiple access schemes (such as TDMA, FDMA and CDMA). The mathematical model can also be applied to the modeling of signal superposition in multipath conditions.
Key words: electronic reconnaissance, antenna arrays, signal superposition, multipath, spatio-time-frequency signal analysis.
