I have some questions about frame construction in the example "Packet-based Digital Link" from here (and in the frame construction and it's aplication in general): https://decibel.ni.com/content/docs/DOC-18801
The pramaters of the transmitter and receiver frame look like this:
Now my questions are:
Sadly I don't have any documentation describing the issues with this example and I'm not able to deduce why the programmer applied these things and how specifically they are captured. Could someone familiar with programming in Labview deduce something from the code?
Here is the code for transmitter:
Sub VIs (in links, for clarity of the post):
subGeneratePackets.vi
sub_calcpadding-symbolrate.vi
sub_generate_packet_array.vi
sub_PSKMod.vi
sub_padIQWF.vi
sub_Text_to_bitstream.vi
Here is the code for the receiver:
Sub VIs:
sub_NoiseEst_and_Chop_shell.vi
sub_resamp_and_demod_shell.vi
sub_resample_and_demodulate
sub_check_rx_packet_validity.vi (I think there may be something going on here with the verification of these packets transmitted from the transmitter)
sub_Reconstruct Data Message.vi
sub_Format Rx Data.vi
sub_Init_PSK_at_Rx.vi
If anyone is able to deduce something from the code I posted, I would be very grateful for help in answering these questions, because it would help me a lot in analyzing how the transmitter / receiver works. Thank you in advance!
