In OFDM transmission, frequency selective fading attenuates the received power of specific sub-carrier signals. For this problem, precoded OFDM which performs unitary transformation to the first modulated data symbol sequence before generating the OFDM symbol is one of the solution methods. In this method, we can apply iterative detection. After the first demodulation at the receiver, exchanging symbol replica and minor channel response sub-carrier signals, then, next demodulation process starts again. However, optimum replacement number has not been researched. Although theoretical analysis result has been carried out, it does not match with the computer simulation. In this paper, I propose a new construction method of symbol replica. Then, I show that the theoretical analysis results are almost equal to the computer simulation. Therefore, proposed method can be applied to calculate the optimum replacement number for iterative detection.
