Based on the percentage amplitude mismatch, the approximate BER formula of the Successive Interference Canceller (SIC) is presented with the Gaussian approximation method，and the effect of the amplitude mismatch on the Bit Error Rate (BER) performance is discussed. The loss of BER performance of the SIC is described as the positive number . The formula of the quantifiable analysis on the relation among the percentage amplitude mismatch , Signal Noise Ratio (SNR) and is derived with the Lagrange mean value theorem and the approximate analysis method. The Simulation results show that this quantifiable analysis formula describes the effect of amplitude mismatch on system performance well.
