Abstract

This paper investigates the Bit Error Rates (BER) obtained using different filter types for RF front ends for WCDMA-UMTS mobile radio systems. Most Base Stations use Chebychev or Cauer-Chebychev filters. This paper compares the use of Bessel, Butterworth and Chebychev filters for use as single channel filters in a WCDMA-UMTS radio system. It is shown that even though Bessel filters pass more adjacent channel interference, they result in a significantly lower Bit Error Rate (BER) and insertion loss than the other filter types.
滤波器类型对WCDMA-UMTS移动无线电系统误码率的影响
本文研究了WCDMA-UMTS移动无线电系统射频前端使用不同滤波器类型所获得的误码率。大多数基站使用Chebychev或Cauer-Chebychev滤波器。本文比较了贝塞尔滤波器、巴特沃斯滤波器和切比切夫滤波器在WCDMA-UMTS无线电系统中作为单通道滤波器的使用情况。结果表明,尽管贝塞尔滤波器通过了更多的相邻信道干扰,但与其他类型的滤波器相比,它们的误码率(BER)和插入损耗显著降低。
