Abstract
This paper presents a design of a Turbo decoder experimental platform based on a
fieldprogrammable gate array (FPGA), including mathematical models of the dec
oder, realization of the program based on the FPGA, and analysis of test results
. The system is based on a general hardware platform and modular software design
and provides visualization of the settings of the decoding algorithms and itera
tions. Simulations and actual tests show that the decoder meets the design requi
rements of stability and reliability.
