Our long-term research goal is to model the in vivo wireless channel. As a first step towards this goal, in this paper we performed in vivo path loss measurements at 2.4 GHz and make a comparison with free space path loss. We calculate the path loss by using the electric field radiated by a Hertzian-Dipole located inside the abdominal cavity. The simulations quantify and confirm that the path loss...
Novel path loss and delay spread models with antenna height dependency under indoor stair environment are proposed. According to the persons' posture and location of the mobile device, the antenna height is categorized as three levels: low, medium and high. The path loss is modeled by using minimum mean square error (MMSE) method; meanwhile, both of mean excess delay and RMS delay spread are modeled...
A novel MIMO model based on singular value decomposition of matrix is proposed in this paper. A corridor to stair MIMO measurement at 2.6GHz is conducted in order to evaluate the performance of the novel model. The joint DoA-DoD-delay power spectrum and the channel capacity of the model are compared with those obtained from the measured channels. The results show clearly that the joint DoA-DoD-delay...
