Abstract
This paper reports our implementation of an experimental system to generate DB-T2 signal based on a commercial FPGA (Field Programmable Gate Array) board with additional instruments. The baseband OFDM (Orthogonal Frequency Division Multiplexing) samples are computed offline via a C program. The OFDM samples are stored in an SD card for the FPGA board to read. The FPGA board converts the digital samples to analog baseband signal to be modulated by an I/Q modulator. The generated DVB-T2 signal can be successfully decoded by a commercial DVB-T2 receiver card, and thus the experimental system is validated.
