Antenna and Propagation Models
Antenna and Propagation Models provide behavioral models for antenna and radio channels. Antenna models are identified by their coordinate and gain. For mobile antennas, the velocity vector is also included in the parameters. Antenna models have multiport input to provide flexibility in summing the contribution from noise and fading channels.
Propagation channel models are typically identified by the type of fading, the power delay profile specification, and the path loss. Channel models are typically statistical in nature. Included in the library are specific models for wireless standards such as GSM, CDMA1, TDMA, EDGE and W-CDMA, as well as general (user-defined) models where the channel is defined by specifying the "delay profile".
Product Highlights
- Provides models of signal propagation effects for system-level analysis of mobile communication products
- Offers propagation environment that is in compliance with major cellular standards
- Provides the capability to simulate spatial diversity scenarios with multiple transmit or receive antennas as well as interference due to the proximity of the receive antenna to an interfering transmitter
Antenna and Propagation Models help designers of mobile communication products examine how the dynamic radio signal propagation channel affects the performance of the system. The models provided are compliant with the following cellular industry standards: GSM (all scenarios), IS-97 CDMA, and IS-54 TDMA, WCDMA and EDGE.
Each model has an option for urban, suburban, and rural path loss prediction. The models are based on a statistical treatment of electromagnetic equations governing radio wave propagation. The models aid in evaluating the entire wireless system link (transmitter/channel/receiver). Also included are base station and mobile station antenna models. These antenna models accept information on location, elevation, vehicle speed, and directional velocity. When used in a simulation, the radio propagation between two or more antennas is statistically modeled to produce multipath effects with Rayleigh and Rician probability distributions.
Antenna and Propagation Models are integrated into the Ptolemy Element.
