| 摘 要： | 研究了一种快速有效的算法用来加快预失真算法的收敛速度,即线性迭代法。并通过计算机仿真来验证这种方法的有效性和可行性,通过计算机的仿真可以使三阶交调分量抑制大概15个dB。理论分析和仿真结果可以表明,该算法使功率放大器的线性化得到很好的改善。

A Fast Predistortion Arithmetic |
| |
| Abstract: | In the modern wireless communication system,the more fast speed of transmission and the much higher rate of spectrum are required. The linear modulation technology and multi-carrier wave technology are used extensively. But the envelope of the two kinds of signals are fluctuating,then it may cause the inter-modulation when it goes through the amplifier. So the linearity of the PA is studied much more. The self-adaption predistortion arithmetic is a compensation of the nonlinear caused by the PA,in this essa... |
