高速成形滤波器的设计与实现

Design and implementation of high speed pulse shaped filter

结合TCM/8PSK高速调制解调器的要求,设计并实现了速率高达300Mbps的波形成形滤波器和相应的数模转换器。提出了一种基于分布式算法结构的新型滤波器结构,解决了FPGA中滤波器的高速计算问题。实验结果表明本文的结构可行,同时对其他领域也有应用价值。

The design and implementation structure of high-speed pulse shaped filter is discussed in this paper. Combined with the request of the high speed TCM/SPSK modem, the data rate is up to 300Mbps. The relevant DAC is also involved in this paper. In practical implementation, a new structure of filters based on the distributed arithmetic is proposed as to solve the problem of high-speed computing in the FPGA. The results show that this structure is feasible, and is valuable in others.
