Design and verification of a testing platform for implementation of software defined radio communications systems
The software-defined radio platforms that currently exist are mainly focused on the development of software communication blocks, leaving aside the hardware development, so the need arises to have a testing platform for hardware blocks which also allows us to interact with a radio frequency stage to perform blocks tests of complete communication systems in the air such as WiFi, Bluethoot, Zig Bee among others. This article describes the design of a platform based on a Field-Programmable Gate Array (FPGA) technology and microprocessor, which allows having multiple blocks and algorithms in hardware and software and interacting between them. In the same way there is a significant number of general purpose interfaces for testing the signals, as well as having specific interfaces which allow us to interconnect with different radio frequency platforms and communication cards with the computer. This allows you to work with different radio technologies according to your needs. A use case is presented in which a Bluethoot transmitter is tested with the use of the platform.
