摘要:
无线数字通信中,内插滤波器用来对基带信号进行脉冲成型滤波,以限制发送信号的带宽,降低带外干扰.研究一种应用于无线数字传输系统的高速FIR成型滤波器的设计方法,该方法采用分布式查找表算法,以降低硬件开销和提高处理速度为目标,是基于现场可编程门阵列(FPGA)并实现升余弦滚降基带成型内插滤波器的硬件电路.最后,通过实测波形与仿真波形证实方法的优越性.
Abstract:
In wireless digital communications,base-band signals are specially shaped using interpolated filter to suppress out-band interferes.Design methods of a high speed FIR shaping filter applied in wireless digital transmission systems are discussed in detail.Hard ware circuits for raised-cosine roll-off pulse shaping filter based on FPGA are implemented ac-cording to distributed lookup table algorithms aiming to lower expenses and increase working speed.The superiority of the methods was proved through the conformity of results obtained from experiments and simulations.
