چکیده

This paper discusses the implementation of modulation chains for multi-standard communications on a dynamically and partially reconfigurable heterogeneous platform. Implementation results highlight the benefit of considering a DSP/FPGA platform instead of a multi-DSP platform since the FPGA supports efficiently intensive computation components, which reduces the DSP load. Furthermore, partial dynamic reconfiguration increases the overall performance as compared to total dynamic reconfiguration since there is 45% of bitstream size reduction, which leads to a 45% decrease of the whole reconfiguration time. The implementation of modulation chains for multi-standard communications proves the availability of new technology to support efficiently Software Defined Radio.

Dynamic Cognitive Radios on the Xilinx Zynq Hybrid FPGA

Cognitive radios require an intelligent MAC layer coupled with a flexible PHY layer. Most implementations use software defined radio platforms where the MAC and PHY are both implemented in software, but this can result in long processing latency, and makes advanced baseband processing unattainable. While FPGA based SDR platforms do existed, they are difficult to use, requiring significant engin...

Dynamic Reconfiguration Technologies Based on FPGA in Software Defined Radio System

Partial Reconfiguration (PR) is a method for Field Programmable Gate Array (FPGA) designs which allows multiple applications to time-share a portion of an FPGA while the rest continues to operate unaffected. As a result, the physical layer processing architecture in Software Defined Radio (SDR) systems can benefit from reduced complexity and increased design flexibility, as different waveform a...
