Since statistical channel models fail to reproduce the intracluster parameters due to the site-specific nature of the millimeter-wave (mmWave) channel, in this letter, we propose a ray-tracing intracluster model for mmWave channels. The model considers only the first-order reflection; thereby reducing the computation load while capturing most of the energy in a typical stationary mmWave system. The model accounts for diffuse scattering as it contributes significantly to the received power. In the simulation result, we validate the model comparing with the measurement-based IEEE 802.11ad intracluster model for a conference room environment. The proposed model gives insight into the mmWave beamformer design and can be used for both indoor and outdoor mmWave systems in static environments, such as living, conference, and office rooms, rural areas, etc.
