essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the TAG of patent information that might be relevant to the standard is essential to
reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair
<[email protected]> as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being
developed within the IEEE 802.19 TAG. If you have questions, contact the IEEE Patent Committee Administrator at <[email protected]>.

Abstract
• The purpose of this presentation is to introduce the
ERO Monte Carlo radio modelling tool SEAMCAT to
IEEE 802.19.
• If the group feels this tool could be of use for their
methodology document then it is proposed that a more
detailed technical presentation would be made at the
London Interim in January 2007.

SEAMCAT Background
•
SEAMCAT (Spectrum Engineering Advanced Monte Carlo Analysis Tool)
was developed in CEPT as a co-operation project between NRAs, industry and
ERO.
•
The first release of SEAMCAT was finalised in January 2000, second release was
made available February 2003 . The latest official version SEAMCAT-3.
•
Since 5 September 2002, the ERO is responsible for overall management of
SEAMCAT project. Additional technical expertise for support of the project is
drawn through the so called SEAMCAT Technical Group (STG) within the CEPT
WGSE.
•
SEAMCAT is based on Monte-Carlo random generation, the theory of which can
be seen in ERC Report 68, which was used in the development of the tool.

SEAMCAT General Features
• SEAMCAT is a flexible tool for analysis of a variety of
compatibility scenarios, and it offers some particularly important
features:
– quantification of interference levels
The level of interference between different radio systems is expressed in
terms of a probability that the reception capability of the receiver under
consideration is impaired by the presence of an interferer.
– consideration of spatial and temporal distributions of the received
signals
This is helpful in developing appropriate frequency planning arrangements
or necessary limits for transmitter/receiver parameters.
– SEAMCAT can address any interference scenario regardless of the
type of victim and interfering radio systems.

SEAMCAT General Features cont.
– Sharing and compatibility studies
Between different radiocommunications systems operating in the
same or adjacent frequency
– Evaluation of transmitter and receiver masks
– Evaluation of limits for certain radio parameters
Such as unwanted emissions (spurious and out-of-band), blocking
and intermodulation levels

SEAMCAT current release
•
The upgrade of SEAMCAT software into its 3rd phase (called
SEAMCAT-3) that took place in 2003-2005, had the following main aims:
– Porting of software to open Java® platform, with introduction of Live Web update
and similar new functionalities;
– Improvement of interactivity of simulations through the graphic representation of
scenarios;
– Implementation of algorithms for direct simulation of CDMA systems, both as
victim and interferer;
– Implementation of plug-in modularity (Propagation model plug-in as well as
generic Post-processing plug-in);
– Improved functionality for complex simulations (limitless batch, remote
computing).

SEAMCAT future plans
• Further updates are planned these include:
– Opening source code for public scrutiny;
– OFDM simulations;
– Moving all user documentation/help to WIKI.
•
ERO welcomes any proposals for implementation of
new functionalities in SEAMCAT.
