This work presents a time-varying multi-BAN channel model implementation including both on-body and Bodyto- Body links. Channel time correlation properties are modeled with an auto-regressive method with the exception of Body-to- Body short term fading. This last component shows an important dependence on the body positions and specifically on the mutual orientation of the bodies. For this reason it requested a dedicated implementation with a Cholesky decomposition based method. Simulated results of the implementation are validated with measurements and a good agreement between the two is found.
