QPSK_ray

matlab code from in the problem in numerical caculation.

说明：  自适应抵消法程序，最小二乘法（LMS）自适应滤波器，噪声抵消(Adaptive canceling procedures, least square method (LMS) adaptive filter, noise cancellation)

这个主要是这对工业区预测编的程序，考虑的是GM（1,2）这种方式，如果是GM（1，n）可以改动一下就可以了。(This mainly Industrial Zone forecast compiled program, consider the GM (1,2) In this way, if the GM (1, n) can be changed and click on it.)

generation of wideband and high dynamic range analog signal for area-efficient MADBIST, especially for the on-chip testing of wireless communication IF digitizing sigma–delta modulator chip. Via increasing the order of the one-bit bandpass sigma–delta modulation algorithm up to 12 and using finite repetitious bitstream approximating scheme, it can achieve great improvements in signal bandwidth instead of purity at the cost of very little hardware overhead. Another contribution in this work is to provide the theoretical analysis of the reconstructed signal degradation due to harmonic distortion and clock jitter. Such on-chip analog stimulus generation scheme is especially fit for IF digitizing bandpass sigma–delta modulator chip s production-time testing and in-the-field diagnostics. The technique can also be extended to mixed-signal communication SoC built-in-self-test.
