Description: 功率放大器原理.近几十年来，在研究宏观和微观世界的过程中，科学家们不断开发能把淹没在噪声中的大量有用信息检测出来的理论和方法，通过不断的系统化，完整化，从而形成了一门新的微弱信号检测的学科分支。锁相放大器的出现使得微弱信号检测步入了一个新的台阶。锁相放大技术在物理、化学、激光、电子、生物医学等方面有着极为广泛的应用。它主要是利用噪声、信号的时间特性不同,设法得到抑制噪声和干扰发现微弱信号的检测方法。 锁相放大电路可以使仪器抑制噪声的性能提高好几个数量级，具有极强的抗噪声性能。它是把待检测的信号中与参考信号同步的信号放大并检测出来。 鉴于现在的锁相放大器体积过大，成本高等因素，可以设计一个基于AD630芯片的锁相放大电路，用来实现一些微弱信号检测，并且可以应用到某些系统当中。-The principle of power amplifier

Description: Quadrature ampliltude modulation has high spectral efficiency but is highly sensitive to power amplifier
nonlinearities. It is shown that an adaptive predistorter usig polynomial amplitude and phase
predistortion functions can be used to linearize the power amplifier. Tie recursive least square algonrthm
is employed in an estimator which uses demodulated signals to estimate the required predistortion.
Computer simulation results are provided and these results show that fast convergence and high spectm
improvement can be obtained using the proposed linearization method. The results are significantly
better than those reported before for other linearization techniques.
