There is a significant gap between the concept of a wireless system and the realization of that working design. Bridging this gap typically involves teams of engineers with a variety of different skill sets (RF, SW, DSP, HDL, embedded Linux, etc.), and in many cases projects get de-railed early in the development stage because of difficulty in coordinating the efforts of these varied design entities.
In this four-part paper we will examine the advances in platforms and tools which allow developers to quickly simulate and prototype wireless systems while establishing and maintaining a…show more content… The third part will describe and showcase how to use Hardware in the Loop (HIL), capturing signals with the target transceiver, but still doing the signal processing on the host in Simulink for verification. The fourth part will show how to take the algorithm developed in part 2, verified in part 3, and use MathWorks HDL Coder and Embedded Coder to generate code and deploy it in the production hardware, and finally we’ll operate the platform with real-world ADS-B signals at an airport.
With the exponential growth in the ways and means by which people need to communicate, modifying radio devices easily and cost-effectively has become business- critical. Based on this requirement, Software Defined Radio (SDR) technology has been widely employed recently, since it brings the flexibility, cost efficiency and power to drive communications forward . The purpose of a SDR system is to implement as much as possible of the modulation /demodulation and data processing algorithms in software and reprogrammable logic so that the communication system can be easily reconfigured just by updating the software and the reprogrammable logic and not making any changes to the hardware platform.
With the advent of the System on Chip (SoC) devices like the Xilinx® Zynq® All Programmable SoC that combine the versatility of a CPU and the processing power of an FPGA,
