| 摘 要： | 预失真技术已经成为功率放大器线性化的一项重要技术,受到广泛的研究与应用。传输信号在学习回路中存在的延时影响了数字预失真算法的线性化性能。在分析传输时延对预失真算法影响的基础上,改进了时延估计算法,并将其应用在数字预失真技术中。通过仿真测试,验证多步插值时延估计算法的有效性。在预失真线性化技术中采用时延估计,能有效克服传输时延的不利影响,充分实现预失真技术的线性化性能,进一步改善功率放大器的非线性特性。

| Abstract: | Predistortion has been a promising technique to linearize power amplifiers. But the time-delay in transmission circuit affects the performance of predistortion. The paper does a research on the time-delay,and improves an algorithm of time-delay estimation. Simulation results demonstrate that the proposed algorithm is effective,and could be used in predistortion linearization technology. The predistortion with time-delay estimation could overcome the disadvantages of time-delay,and improve linearization performances of power amplifier. |
