本程序是LM方法实现的主程序，并且本程序通过了LMFnlsq2test.rar程序的测试，证明了程序的正确性和有效性。顺便说下，上面的LMFnlsq2test.rar里面的程序是一个测试程序，它的描述写错了。(This LM method is the main program, the program and the program passed LMFnlsq2test. Rar program test, proves the correctness and effectiveness of the program.. By the way, the above LMFnlsq2test rar program is a test program, a description of the write it wrong.)

Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers, one exactly 90 degrees out of phase with respect to the other, are used to transmit data over a given physical channel. One signal is called the I signal, and the other is called the Q signal. Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase shift, each can be modulated independently, transmitted over the same frequency band, and separated by demodulation at the receiver. For a given available bandwidth, QAM enables data transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation in the bit error ratio (BER).
