Return Information for Ray-Tracing Channel Between Two Sites in Hong Kong
Perform ray tracing between two sites in Hong Kong, China, build a multipath channel model using the ray-tracing result, and view the ray-tracing channel information.
Create a Site Viewer map display of buildings in Hong Kong. For more information about the osm file, see [1].
sv = siteviewer("Buildings","hongkong.osm");
Create transmitter and receiver sites.
tx = txsite("Latitude",22.2789,"Longitude",114.1625, ... "AntennaAngle",30, ... % azimuth "AntennaHeight",10,"TransmitterFrequency",28e9); rx = rxsite("Latitude",22.2799,"Longitude",114.1617, ... "AntennaAngle",120, ... % azimuth "AntennaHeight",1);
Perform ray tracing to find rays with up to 2 reflections.
rays = raytrace(tx,rx,"NumReflections",[0 1 2]);Create a channel model by using the transmitter site, receiver site, and calculated rays between the sites. Return information from the ray-tracing channel.
rtchan = comm.RayTracingChannel(rays{1},tx,rx);
