The W1715 MIMO Channel Builder provides multi-channel fading simulation blocks that incorporate realistic antenna patterns for LTE system architects, receiver algorithm developers, and baseband hardware designers. It consists of a geometry-based WINNER-II MIMO channel model and a correlation-based MIMO channel model, thus adding standards-compliant 4G fading profiles to the Keysight SystemVue platform. It interoperates well with the W1910 LTE Baseband Verification Library, as well as other Keysight measurement products, such as the 89601 VSA, N5106A PXB source, and other products. The W1715 MIMO Channel Builder also provides an economical, predictive alternative to real-time hardware faders for up to 8x8 MIMO links.
Why should I buy the W1715 MIMO Channel Builder?
- Develop, verify, debug LTE receiver algorithms
- Generate highly-parameterized test vectors and regression suites
- Predictive, accurate, configurable, economical alternative to hardware faders
- Interacts equally well with Algorithms (C++, math), or Test equipment, such as the Keysight N5106A (shown below), for design flow confidence and continuity
- Sharable across distributed design teams
Enabling Predictive “drive-test realism” in the Algorithm Phase
The W1715 MIMO Channel Builder starts with published geometry-based WINNER-II and Correlation-based MIMO fading algorithms, extending each underlying SISO model with correlation-based fading after each tap. The MIMO Channel Builder then incorporates 2D far-field EM data into the propagation characteristics of the simulated MIMO radiators. The simulated fading blocks degrade MIMO signals with near-field crosstalk that is precise, realistic, and predictive. When combined with other SystemVue advantages, such as fast envelope-level RF effects and HARQ throughput measurements, the result is unprecedented link-level fidelity for LTE architects that yields predictive insights much earlier in the design process for superior partitioning and algorithmic development. SystemVue brings drive-test realism into the architecture phase of the design, before hardware has been implemented.
Who should use Keysight’s W1715 MIMO Channel module?
LTE architects can use the W1715 MIMO Channel Builder to predict and track the link-level system performance during a complex design process, despite challenges such as partially completed RF hardware, evolving antenna and packaging designs, and evolving standards and algorithmic research.
Receiver designers have the ability to create precisely-degraded, standards-compliant test vectors necessary for development and “vetting” of robust receiver algorithms. With full parameterization, the W1715 MIMO Channel Builder models help SystemVue users to verify 4G receivers at all levels of abstraction: math or C++ languages, VHDL/Verilog. Waveforms downloaded to test equipment (such as the Keysight N5106 PXB) and the exact same verification performed directly in measurement equipment.
Keysight SystemVue provides a convenient system-level communications design “cockpit” to initiate the design, hand off to a variety of corporate design flows for implementation, and verify the finished hardware results. SystemVue’s unified ESL approach to communications accelerates the design maturity, helps reduce inefficient design margins, and delivers more robust designs from the very first generation.
