| Abstract: | 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. |
