通用调制解调程序，主要包括BPSK, QPSK, 64QAM, 64QAM等常用调制方式。(Generic modem program, including BPSK, QPSK, 64QAM, 64QAM modulation, such as commonly used.)

通过FIR滤波器的自适应调整，不断修正其系统函数，使其与未知系统的参数充分逼近，从而使误差最小，达到系统辨识的目的。(Through the adaptive FIR filter, and continuously revise its system function, so that the unknown system parameters with sufficient approximation, so that the smallest error to achieve system identification purposes.)

Comparison of two survival curves can be done using a statistical hypothesis test called the log rank test. It is used to test the null hypothesis that there is no difference between the population survival curves (i.e. the probability of an event occurring at any time point is the same for each population).
