LTE PHY Lab is implemented according to TS 36.211-870, TS 36.212-870 and TS

36.213-870. 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, OFDMA and SCFDMA signal generation. Thanks to that, baseband models of

both the eNB and also the UE, 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 LTE 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.

LTE PHY Lab is a comprehensive implementation of the 3GPP Release 8 E-UTRA

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. LTE PHY Lab can be

used at all stages of the LTE software, hardware and IPR development, from research,

prototyping and implementation, up to system benchmarking, verification and testing.

Together with selling the LTE PHY Lab, we offer the unrivaled customer support service

including tracking of the 3GPP specs, bug fixing, integration support and customization

of the design.

R&D, prototyping and design of PHY layer baseband functions and algorithms i n c l ud i ng p rop r i e t a r y implementations and IPR, where LTE PHY Lab shortens the development time.

Development of RF elements and design of higher layers (e.g. MAC) and protocols, where LTE PHY Lab serves as a reference PHY layer model.

Testing and verification of the developed algorithms or complete equ ipments , where LTE PHY Lab provides test and reference signal vectors.

Education, including specia-lized technical trainings, as well as university classes, where LTE PHY Lab can be used to enrich theoretical sessions by providing the real demonstrations of the LTE PHY layer behavior.

>01 INTRODUCTION :/ /

The LTE 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 LTE PHY Lab are presented in the figures 2-4.
