The coder part of the FPGA receives the processed transport stream signals and per-
forms the FEC for the selected digital TV standard. The subassembly generates digital
I/Q signals which are forwarded to the RF section.
Using the AWGN software option (R&S
SFE100-K40 noise generator), additive white
Gaussian noise (AWGN) can be generated.
3.1.2 RF Section
The D/A converter converts the digital signal into an analog I/Q signal. This analog I/Q
signal feeds the I/Q modulator. The following part contains the synthesizer, output sec-
tion with I/Q modulator, and attenuator.
The frequency range is 100
kHz to 2.7
GHz.
