Frame-based Modeling for Automatic Synthesis of FPGA-Software Defined Radio

Abstract

Software Defined Radio (SDR) is now becoming a ubiquitous concept to describe and implement Physical Layers (PHYs) of wireless systems. Moreover, even though the FPGA is expected to play a key role in SDR, describing a PHY at the Register-Transfer-Level (RTL) requires tremendous efforts. This paper introduces a novel methodology to rapidly implement PHYs for SDR. The work relies upon High-Level Synthesis tools and dataflow modeling in order to infer an efficient RTL control unit for the application. The proposed software-based over-layer partly handles the complexity of programming an FPGA and integrates reconfigurable features. It consists essentially of a Domain-Specific Language (DSL) combined to a DSL-Compiler. An IEEE 802.11a transceiver has been explored via this approach in order to show the flexibility features.

Study of the Impact of the Magnetic Field on the Electrical Parameters of the Radial Junction Photovoltaic Cell under Monochromatic Illumination

“…To better understand the behavior of a radial junction photovoltaic cell, we will investigate the influence of the magnetic field on the photocurrent, photovoltage and electrical power of our physical cell model. Several authors have conducted similar studies to determine the influence of the tilt angle, such as Sahin [1] on a parallelepiped cell with a vertical junction, Sourabi é [2] on a bifacial cell and Ou édraogo [3] on the influence of a radio wave on a parallelepiped photovoltaic cell. Indeed, this geometry of the photovoltaic cell favours the absorption of almost all the incident light above the band [4] [5] due to its radial junction.…”

Design and Realization of Variable Digital Filters for Software-Defined Radio Channelizers Using an Improved Coefficient Decimation Method

“…Multiple SDR test beds make use of FPGA capabilities for accelerating baseband computation and run-time adaptation like IRIS platform [6] and WARP [7]. In [8,9], the authors presented high-level synthesis based methods for direct mapping of SDR description in MATLAB/Domain Specific Language (DSL) to system architecture on FPGA. In [10], the authors presented a closely coupled SDR based cognitive radio platform based on the Zynq FPGA with high-speed software-based hardware reconfiguration and simple API controls for managing them.…”

On the FPGA-Based Implementation of a Flexible Waveform from a High-Level Description: Application to LTE FFT Case Study

“…FPGA-based SDR is an old paradigm [8] offering a good tradeoff between reconfiguration capability and processing power. Fast prototyping capability of an FPGA-based SDR is achieved by leveraging High-Level Synthesis (HLS) principles and tools to generate Register-Transfer Level (RTL) descriptions from high-level specifications [18]. However, the issue of run-time flexibility is still opened.…”
