This paper presents a hardware scheme based on FPGA to implement the 3780 points FFT. The simulation result shows that this design can satisfy the requirement of the DTTB transmitter and can acquire the better performance than typical schemes.
This paper gives a channel coding solution which meets the national standards of mobile multimedia broadcasting, the result of simulation shows that QC-LDPC has a good performance while the signals with a extremely low SNR transmitted in AWGN channel. According to the standards, it analyzes the method of implementing the QC-LDPC with FPGA. For the specialty of the quasi-cycle coding matrix, it adopt...
