A concept concerning correlation properties of superposition sequences is proposed. And so, an optimized selection method is proposed based on analysis of correlation properties of superposition sequences for Gold sequences. According to the property of the relatively large multiple peaks of the cross-correlation functions, the smaller cross-correlation characteristic peak values of superposition sequences are optimized to decrease mutual interference of superposition sequences in asynchronous system. It is shown that the bit error probability is lower than that of non-optimized selection Gold sequences in additive white Gaussian noise channel of the asynchronous system.
