The dense multipath components (DMCs) are non-resolvable distributed multipaths on the spatio-temporal domain that cannot be modeled as specular propagation paths. The specular paths are modeled by ray-optical propagation, while the DMCs originates from electromagnetic field scattering and are diffusive. The DMCs have a significant impact on multiple-antenna link performance. This paper presents a DMC add-on for the existing implementation of COST 2100 channel model in MATLAB. The DMC implementation is based on a geometrical approach which is simple and consistent with the specular path modeling. In the delay domain, the DMCs are associated with an exponentially decaying power delay profile. Whereas in the angular domain, DMCs are dropped uniformly in an extended three-dimensional ellipsoid of the specular cluster so that they are centered at the same angles as specular paths but with wider angular spread. Parametric study of the DMC shows its implication on the delay spread of wideband channels and on the eigenvalue distribution of multiple-antenna channels.
