“…Software Radio is a new architecture for wireless communication based on digital signal processing and microelectronics technology. [9] In this paper, an ARM and FPGA based software radio platform is designed according to the needs of actual system in digital signal processing and wireless communication, which take full advantage of the flexibility of ARM and the parallelism of FPGA. The choice of ARM is Freescale s IMX6, which has a rich instruction set and programming flexibility; FPGA has a great advantage in the speed and parallel computing, suitable for requirements for real-time data transmission.…”

Abstract. The rapid rise in computational performance offered by computer systems has greatly increased the number of practical software radio applications. A scheme presented in this paper is a software radio platform based on ARM and FPGA. FPGA works as the coprocessor together with the ARM, which serves as the core processor. ARM is used for digital signal processing and real-time data transmission, and FPGA is used for synchronous timing control and serial-parallel conversion. A SPI driver for real-time data transmission between ARM and FPGA under ARM-Linux system is provided. By adopting modular design, the software radio platform is capable of implementing wireless communication functions and satisfies the requirements of real-time signal processing platform for high security and broad applicability.

“…Flexible implementations of specific radio blocks using PR, such as adaptive filters, have also been demonstrated [Choi and Lee 2006;Pham et al 2017]. Cognitive radios are more advanced SDRs that modify their own functionality at runtime in order to operate more effectively in unknown environments [Delorme et al 2008]. Adaptation of the modulation scheme, coding, filters, and other baseband features at runtime necessitates low power hardware implementations that are also flexible.…”

Dynamic and partial reconfiguration are key differentiating capabilities of field programmable gate arrays (FPGAs). While they have been studied extensively in academic literature, they find limited use in deployed systems. We review FPGA reconfiguration, looking at architectures built for the purpose, and the properties of modern commercial architectures. We then investigate design flows, and identify the key challenges in making reconfigurable FPGA systems easier to design. Finally, we look at applications where reconfiguration has found use, as well as proposing new areas where this capability places FPGAs in a unique position for adoption.

Today, wireless devices generally feature multiple radio access technologies (LTE, WIFI, WIMAX, ...) to handle a rich variety of standards or technologies.These devices should be intelligent and autonomous enough in order to either reach a given level of performance or automatically select the best available wireless technology according to standards availability. On the hardware side, system on chip (SoC) devices integrate processors and field-programmable gate array (FPGA) logic fabrics on the same chip with fast inter-connection. This allows designing software/hardware systems and implementing new techniques and methodologies that greatly improve the performance of communication systems. In these devices, Dynamic partial reconfiguration (DPR) constitutes a well-known technique for reconfiguring only a specific area within the FPGA while other parts continue to operate independently. To evaluate when it is advantageous to perform DPR, adaptive techniques have been proposed. They consist in reconfiguring parts of the system automatically according to specific parameters. In this paper, an intelligent wireless communication system aiming at implementing an adaptive OFDM-based transmitter and performing a vertical handover in heterogeneous networks is presented. An unified physical layer for WIFI-WIMAX networks is also proposed. The system was implemented and tested on a ZedBoard which features a Xilinx Zynq-7000-SoC. The performance of the system is described, and simulation results are presented in order to validate the proposed architecture.
