摘要:
预失真技术是克服功率放大器非线性失真的一种很有效的方法.采用最小二乘法(LS)算法的预失真技术可以获得很好的功率放大器线性化性能,但是其中的矩阵求逆运算在硬件上实现比较困难.论文采用坐标旋转数字计算算法(CORDIC)实现QR分解,并应用在预失真技术中,获得了较好的放大器线性化性能.通过在可编程逻辑阵列(FPGA)硬件平台上的仿真,验证了方法的可行性和有效性.
Abstract:
Predistortion technology is an effective method to overcome the nonlinearity of power amplifier.It can achieve a satisfied linearization performance by using LS method.But the matrix inversion is hard to implement on hardware.The paper uses QR decomposition into LS method,and achieves a better linearization performance.In the end,simulation result demonstrates that the predistortion method is effective.
