A root mean square (RMS) delay spread model in indoor femtocell scenarios is proposed. The proposed model is based on extensive channel sounding of indoor stair, corridor and office environments. In this model, the RMS delay spread is described as a linear function of the path loss, and a normal stochastic variable is introduced and utilised to characterise the deviation of the measured RMS delay...
A novel empirical path loss model for indoor stairwell environment is presented. The model is based on the multiple-input-multiple-output (MIMO) measurements at 2.6 GHz. The model is divided into two scenarios, i.e., line-of-sight (LOS) and non-LOS (NLOS). In the case of LOS, the path loss exponent n is dependent with the increasing of frequency slightly and is fitted by the frequency using power...
Mutual coupling effect affects capacity of compact MIMO system. Using scattering parameter matrix (S-Matrix), this paper analyzes capacity of compact MIMO system and makes simulations on capacity using three different structural antenna arrays and three matching networks. Numerical results based on method of moment (MOM) show that antenna space with half wavelength is the dividing point of tightly...
This paper models compact MIMO system recurring to microwave network, theory. Using scattering parameter matrix (s-matrix), it analyses the ability of suppressing mutual coupling effect and power exporting ability of compact MIMO antenna arrays. Simulations have been done on four different types of antenna arrays which respectively are parallel double dipoles, vertical double dipoles, double X-shaped...
