The use of programmable logic devices, especially FPGA's and CPLD's, is becoming very common. This devices can have in the future an impact as important as the microprocessor had in the past. Telecommunication systems can have great advantages by the use of programmable logic devices. The main subject of this thesis is the creation of a platform that allows the simulation, development, and testing of digital radio systems, taking advantage of the versatility of programmable logic devices. A board was built with a programmable device, software was written for the communication between the board and an PC, and some essencial algorithms were implemented using VHDL. After an introduction to the basic concepts of digital radio, we give a description of this platform and the work performed for this thesis.
