Figure 12: Schematic diagram of the channel for 60 GHz close proximity Model Parameterization List of Parameters The complete list of parameters used in this document can be summarize as follows: 1. K factor of Rice distributions for the first arrival tap K, 2. the decay rate for the delayed taps , 3.  initial between the first tap and delayed taps As simulation scenario, there above parameters are introduced under the conditions that polarizations between the transmitter and the receiver are aligned. Parameterization for 57 66 GHz – Proposer shall report values of parameters, that is used in the performance evaluation K, γ, δ, simulation. Simulation Scenario In this section, we describe how to simulate multipath fading effects on transmission performance of proposed wireless system in IEEE802.15.3e. These scenarios are for reference only; other scenarios which provide the same principle as the following will be admissible. Maximum tap space Regarding signal bandwidth (BW), 15.3e channel models assume that maximum tap spacing can be represented by , (4) 2. where N is assumed to be 1.76 GHz in IEEE802.15.3e, so can be calculated to be 0.2841 BW tap-space nsec. Concerning the case where signal bandwidth is expanded due to channel bonding, tap spacing, shall be reduced by the factor of 2Bonding-BW/BW, where is tap-space, Bonding-BW the new signal bandwidth. Number of multi-path The number of multi-paths varies depending on the environment. Based on initial measurements the number of multi-paths are counted to be about between 1 to 8. We suggest that the number of multi-paths be arranged related to reflective objects around a transmitter and a receiver.
