AB  - In this study, the design and implementation of Coded Orthogonal Frequency Division Multiplexing
(COFDM) system is presented. The design of COFDM system-level is done by using MATLAB/Simulink while
the implementation is based on TMS320C6713 DSK from Texas Instruments Inc. The collaboration of MATLAB
Integrated Development Environment (IDE) and Code Composer Studio (CCS) are adopted. The real time
implementation is one of the most difficult issue of OFDM implementation The problem of real time
implementation is the memory consumption and the processing time. The other problem is synchronization of
OFDM receiver. Time and frequency synchronization to distinguish the begin of the OFDM symbol. The
transceiver performance is evaluated based on Real-Time Data Exchange (RTDX) with Additive White Gaussian
Noise (AWGN) channel with using channel estimation method. In addition, the designed system is investigated
with the convolutional encoder of 1/2 Punctured-6/7 code rate with block interleaving. The data rate 9.6 kB/sec,
processing time 4 msec and the bit error rate performance for SNR 10<sup>&#150;1</sup> = 2 dB and 10<sup>&#150;4</sup> = 12 dB.
