This white paper is Part Two of the MAC/PHY prototyping platform series. The next generation wireless communication networks, or 5G, will need to evolve to overcome the limits of current systems by serving a number of novel use cases with very diverse requirements. With many unknowns, researchers recognize the need to go beyond the computer-based simulation to test the system in the real-world scenario. For such experimental studies, the National Instruments (NI) LTE MAC/PHY prototyping system offers a flexible hardware and software reference architecture complete with a real-time upper layer stack and PHY layer that enables wireless researchers to rapidly prototype networks of LTE devices that communicate over real-world wireless channels. In this white paper, we explain the technical details of the platform, each layer of the communication stack and how to set it up with an open source simulation tool such as Network Simulator 3, NS-3. In the last part of the series, Part Three, we will show the system components to explain what is needed to build such flexible prototyping platform.

This white paper is Part One of the MAC/PHY prototyping platform series. Consumer demand for greater bandwidth continues to outpace the capacity available in present-day networks. The next generation wireless communication networks, or 5G, will need to evolve to overcome the limits of current systems by serving a number of novel use cases with very diverse requirements. For example, to meet the strict low latency performance requirements of network virtualization and ultra dense deployments, all layers of the communication system including the core network must be optimized in a joint manner. This white paper explains the demand and the needs for the testbed for the MAC/PHY platform as well as the applications needs such as testing latency reduction, interference coordination, cancellation algorithm and etc. It also covers the overview of National Instruments’ flexible platform. In the second part of the series, we will dive deep into the technical details.
As high speed serial data rates advance from 15 Gb/s to beyond 50 Gb/s, we face a fundamental shift. Conventional logic-emulating NRZ (Non-Return to-Zero) signaling is being replaced by PAM4, a 4-level pulse amplitude modulation scheme that takes half the bandwidth to transmit the same payload as the equivalent NRZ signal.
PAM4 challenges signal integrity, test, and design engineers who are responsible for SERDES (serializer/deserializer) components, interconnects, backplanes, cables, connectors, circuits, and complete systems.
This paper covers:
- NRZ and PAM4 Bandwidth Demands at High Data Rates
- The Importance of Accurate S-parameters
- Modeling and Simulation of SERDES, Interconnects, and Circuits
- PAM4 Analysis Requires VNA Measurements
