Agilent Technologies has added support for key 4G technologies, such as adaptive modulation and coding (AMC) and coordinated multi-point (CoMP), to its EEsof EDA W1918 LTE-Advanced baseband verification library.
The new modelling and simulation capability enables wireless system architects to model sophisticated dynamic behaviours and realistic performance at cell edges according to the physical layer (PHY) specifications of 3GPP releases 10 and 11. This accelerates the design and verification process for 4G chipsets and infrastructure, enabling faster deployment.
The newly supported 4G technologies enable wireless infrastructure to tailor signals in marginal coverage areas to a particular mobile phone, using adaptive and cooperative techniques that go beyond simple 1:1 interaction between the transmitter and receiver.
This dynamic behaviour makes validation of the PHY algorithms, RF components and link-level throughput progressively more difficult in R&D – both in EDA simulations as well as test equipment – because negotiation and interaction are often required. That is, a complete working system is required to verify baseband algorithms, RF components and throughput under realistic conditions, making this process problematic in early R&D, prior to final hardware integration and test.
The SystemVue simulation environment, Agilent’s premier platform for electronic system-level design, is able to reproduce these conditions in R&D with the help of the W1918 LTE-Advanced library.
