W1918EP LTE-Advanced Baseband Verification Library

The W1918 LTE-A Baseband Verification Library provides industry-leading commercial design support for the physical layer of 3GPP Release 8-13, enabling system and algorithm developers to deploy next-generation 4G performance with greater insight and confidence.

The W1918 optional simulation reference library for PathWave System Design (SystemVue) provides a block set, reference designs, testbenches, and configurable physical layer waveforms and data for 3GPP Releases 8, 9 (LTE) and 10-12 (LTE-Advanced). The library is useful for simulation-based exploration of challenging algorithms, up to 8x8 MIMO throughput verification, and integration with Keysight signal sources and analyzers.

Key Features

• Over 40 new blocks and 8 example workspaces for Narrowband Internet of Things (NB-IoT), as part of the physical layer support for Release 13.2.0 (June 2016)
• Dynamic receiver measurement plots and tables, without requirement of external software
• LTE-Advanced updates: ◦ Support for 256 QAM (both UL, DL)
  - Support for Extended Cyclical Prefix (both UL, DL)
  - Support for closed-loop TM4 TDD/FDD (DL)
  - MMSE and MMSE-IRC for spatial multiplexing (DL receiver)
• NB-IoT (LTE-Advanced Pro) Uplink/Downlink EVM
• W1918 is also included in the W1907 “5G Forward” library bundle
• Includes the W1910 LTE library (LTE release 9.1), and further adds LTE-Advanced algorithmic reference models, providing well over 160 core simulation blocks and nearly 3 dozen reference designs and physical layer verifications, as called out in the standard.

Configuration

The W1918 LTE-Advanced Baseband Verification Library can be added to any SystemVue environment or bundle. It interoperates especially well with the W1715 MIMO Channel Builder model set and the W1716 Digital Pre-Distortion Builder module.
