Library
SEAMCAT library is a useful tool for creating and storing various typical elements of interference scenario and later easily re-using them when creating complex scenarios. The SEAMCAT library allows creating such data templates for the following scenario elements:
- Antennas - might be useful in particular for storing antenna profiles with complex radiation patterns;
- Transmitters and Receivers - useful to store detailed description of typical transmitters and receivers, with complex emission plots, etc;
- CDMA Link level data - contains a set of pre-defined tables and allows user to create its own tables of CDMA link level data, i.e. the data describing required signal-to-noise criteria for CDMA link as a function of some environmental parameters (e.g. the so called 'link geometry', speed of mobile terminals, handover state);
- Propagation model plugins - may be used to create user-defined propagation models;
- Post-processing plugins - which may be used for performing additional, user-defined computations with data produced in each SEAMCAT snapshot.
Modification of existing (default) library elements as well as creation of new elements can be managed through the relevant options of Library menu. Once stored, the library elements may be then easily inserted into scenario by selecting a particular library element in the Definition field for relevant transceiver in either victim or interfering links, as illustrated in the following picture:
Note: Once a library element is invoked into a given scenario, there remains no relational link between the original library element and its copy pasted into the workspace scenario. That is, if at some later stage the user modifies or suppresses the library element, this by itself will not produce any change in replicas of that library element previously pasted into existing workspaces.
