QUASI-ANALYTIC BER ESTIMATION ON THE NON-LINEAR SATELLITE COMMUNICATION CHANNELS |
摘要 |
PURPOSE: A method for calculating a bit error rate in a nonlinear satellite communication channel is provided to calculate the bit error rate exactly by using a quasi-analytic simulation technique. CONSTITUTION: A transmit filter(12) filters a transmit signal of a transmit modulator(11), and a nonlinear amplifier(13) receives an output of the transmit filter(12). A demodulator(15) demodulates an output of the nonlinear amplifier(13) through a receipt filter(14). At this time, a forward link noise is included in a forward link between the transmit filter(12) and the nonlinear amplifier(13), and a backward link noise is included in a backward link between the nonlinear amplifier(13) and the receipt filter(14). Each of a probability density function about the forward link noise and a probability density function about the backward link noise are calculated at an input terminal and an output terminal of the nonlinear amplifier(13). Next, A bit error rate of a receipt terminal is calculated by using two probability density functions through a quasi-analytic simulation technique. In the quasi-analytic simulation technique, the bit error rate is calculated on the basis of a mean of a conditional error probability about a signal sample received through the receipt terminal.
