DART- A HIGH LEVEL SOFTWARE-DEFINED RADIO PLATFORMMODEL FOR DEVELOPING THE RUN-TIME CONTROLLER

by Martin Palkovic, Jeroen Declerck, Praveen Raghavan, Antoine Dejonghe, Liesbet Van Der Perre
"... Novel cognitive radio platforms such as IMECs COgnitive Baseband RAdio (COBRA) should ensure the feasibility of multiple streams and their reconfigurability and scalability during run-time. The control over those tasks should be dedi-cated to a run-time controller that (re)allocates the resources on ..."

In this paper we propose the DAtaflow for Run-Time (DART), the high-level dynamic data-flow platform model framework, suited for rapid run-time control development. We sketch also how to use this framework to develop

Multi-Threaded Processor For Software-Defined Radio

by John Glossner Erdem , 2002
"... In this paper we discuss broadband communications systems and technologies being developed to allow real-time execution using software implementations. We discuss a new multithreaded SDR core designed by Sandbridge Technologies capable of executing RISC, DSP, and Java code. We then describe the soft ..."

the software tools developed for the hardware. We then describe our 2Mbps WCDMA C code implementation and the SB9600 baseband product. We show that it is possible to design communications systems in high-level languages and automatically generate efficient code that runs in real-time on the SB9600

ESL Design and HW/SW Co-verification of High-end Software Defined Radio Platforms

by unknown authors
"... Multiple wireless technologies are converging to run on personal handhelds. The plethora of communication standards next to the cost issues of deeper submicron processing require handheld platforms to shift from sets of multiple application specific ICs (ASICs) to multi-purpose Multi-Processor Syste ..."
Abstract - Add to MetaCart
-Processor System-on-Chip (MPSoC) on which Software Defined Radios (SDR) are run. SDR design faces hard real-time processing and data transfer latency constraints. Designing SDR under stringent time-to-market (cost), energy and real-time processing constraints requires the help of advanced Electronic System-Level

First steps in programming: A rationale for attention investment models.

by Alan F Blackwell - In Proc. HCC, IEEE , 2002

Machine-verified network controllers

by Arjun Guha, Mark Reitblatt, Nate Foster - In PLDI , 2013
"... In many areas of computing, techniques ranging from testing to formal modeling to full-blown verification have been successfully used to help programmers build reliable systems. But although networks are critical infrastructure, they have largely resisted analysis using formal techniques. Software-d ..."

We then use this model to develop a verified compiler and run-time system for a high-level network programming language. We identify

Implementation Transmitter Diversity with Tomlinson-Harashima Precoding for WIMAX IEEE802.16d OSTBC-OFDM Baseband Transceiver on a Multi-Core Software Defined Radio Platform

by Mohammed Aboud Kadhim, Widad Ismail
"... Abstract: WIMAX IEEE 802.16d present direction in the improvement of high-data-rate wireless systems focus on the integration of orthogonal frequency-division multiplexing (OFDM), multiple-input multiple-output (MIMO), transmit precoding reacts to channel conditions in order to improve the system ca ..."

Upgrading the JCMT Control System to Platform Independence

by Mary Fuka A, Dennis Kelly B, Richard Prestage A
"... The James Clerk Maxwell Telescope (JCMT) is escaping from its dependence on VAX/VMS legacy software by incrementally upgrading its control system using platform-independent tools. The first stage of the upgrade includes a GUI, written in Java and modeled on project planning software, for defining co ..."

RcUBe: Real-Time Reconfigurable Radio Framework with Self-Optimization Capabilities

by Emrecan Demirors, George Sklivanitis, Tommaso Melodia, Stella N. Batalama
"... Abstract—Existing commercial wireless systems are mostly hardware-based, and rely on closed and inflexible designs and architectures. Moreover, despite recent significant algorithmic developments in cross-layer network adaptation and resource al-location, existing network architectures are unable to ..."
