Synopsys Inc. has added a time division duplex (TDD) mode in its long-term evolution (LTE) Model Library for physical layer system simulation.
The addition of the TDD mode to the proven LTE model library enables developers of semiconductors for LTE network equipment and devices to extend designs to support the 3rd Generation Partnership Project (3GPP) LTE standard.
Support for both TDD and frequency division duplex (FDD). Synopsys’ LTE library includes models of the transmitter and the physical channel as defined in the 3GPP standard as well as functional models of ideal receivers that can serve as references, providing an end-to-end simulation chain for both uplink and downlink transmission and reception.
By leveraging both FDD and TDD mode models from the LTE Model Library, designers can focus on the development of highly-optimised, multi-mode modems for the entire LTE standard.
The LTE Model Library offers ready-to-use, standard compliant test benches and simulation scripts that cover the test scenarios as defined in the LTE standard document. Models and scripts adhere to release 8.9 of the 3GPP LTE standard and will be upgraded as the standard evolves.
In addition, the reference models in the LTE Model Library have been optimised to take advantage of the stream-driven data flow technology in Synopsys’ SPW and System Studio tools, and are designed to provide a comprehensive and efficient development environment for advanced digital signal processing design.
