WiMAX PHY Lab is implemented according to IEEE 802.16e-2005 (and 802.16d-2004
where necessary) and WiMAX Forum Mobile System Profile Specification Release 1.5. It
includes, from day one, both the downlink and the uplink processing chains covering all
the PHY steps such as FEC, modulation, MIMO processing, resource mapping and
OFDMA. Thanks to that, baseband models of both the Base Station (BS) and also the
Mobile Station (MS), can be easily created. High detail of functional blocks'
implementation allows for
great flexibility in customized
and proprietary designs. In
addition, it is very useful in
applications of the WiMAX PHY
Lab in education, where it is
often important to evaluate the
role of every single component
block. The summary of all the
supported channels and
signals is shown in the
table below.
WiMAX PHY Lab is a comprehensive implementation of the mobile WiMAX physical
layer. It has a form of a Matlab Toolbox for its great flexibility in applications such as
modeling and simulation of the communication systems. WiMAX PHY Lab can be used
at all stages of the WiMAX software, hardware and IPR development, from research,
prototyping and implementation, up to system benchmarking, verification and testing.
Together with selling the WiMAX PHY Lab, we offer the unrivaled customer support
service including tracking of the IEEE specs, bug fixing, integration support and
customization of the design.

The WiMAX PHY Lab functions are easily and broadly parametrizable, and external sources of information can be used to drive the created models (for example to fill out the user plane data). In addition, plenty of examples on how to use the functions are provided, together with the test files and representative channel models.
Some available plots from the operation of the WiMAX PHY Lab are presented in the figures 2-4.
