Dealing with many of users simultaneously and error free communication with maximum utilization of limited spectrum, improved bit error rate (BER) has become very important. Turbo code provides modest decoding complexity for large block length and better bit error rate as compared with other codes. The main part of a turbo code is convolution code. It is one of the best types of the channel coding to increase the data transmission rate at a fixed error rate or error rate could be reduced with a fixed data transmission rate in digital communication systems. One of the most modern parts of a wireless system is the Orthogonal Frequency Division Multiplexing (OFDM), which is one of the multiple modulation systems. The main aim of this work is to study the design and synthesis turbo code with OFDM system. Simulation performance of OFDM design in this paper showed successfully result, which composed of the main parts Serial / Parallel, 8QAM, 16IFFT. System implementation has been done using FPGA technology with Altera Cyclone II boards.
