Dear Olivier, I would like to delete the coding blocks (BCH and LDPC blocks) in the BER simulation in other to obtain the BER after QAM demapper without the presence of parity bit. I would like to know if it is possible like for the Rotated constellation block. If yes, what commands can I use to do this simulation? Thank you in advance for your answer. Best regards, Anne-Carole

Dear Olivier, Thanks for your help. I already read once the white paper. I got the result by inserting ROTCON_BYPASS = 1 in the "run" command and consulting again the "Getting Started".

Dear Olivier, I would like to increase the number of Byte generated by " t2_tx_dvbt2bldatagen(DVBT2, FidLogFile)". But I remark that in the code below, I have the "numBytes" which depend on the START_INT_FRAME and the NUM_INT_FRAMES. The interleaving bloc is one of the next blocs in the system. I don't understand how to put the "numBytes". Can you help me to increase the value "numBytes" to generate? Thanks in advanced for your answer King regards Anne-Carole function DataOut = t2_tx_dvbt2bldatagen(DVBT2,...

Dear Olivier, I would like to assess the performance gain of rotation constellation with the lite version of the CSP. I try to put the angle value of 0 degree but I dont have the result. I remark that in both blocs 't2_tx_dvbt2blconrot' and 't2_rx_dvbt2blrotcondmap', we have the line below BYPASS = DVBT2.PLP(plp).ROTCON_BYPASS; % Bypass rotation How can I use it to disable the rotation contellation bloc in the simulation? Otherwise, can I have another way to disable it? Kind regards,

Ok thank for the information. No it is not a problem. I ready used this thread to plot the BER but to 10^-4

Dear Oliver, I am using the CSP to see its features and to know if it is possible to change one block for the purpose of increasing the DVB-T2 performance. I remarked that the BerTarget=10^-4 is the BER after LDPC. In EN 302 755 v1.4.1 standard, the BER after LDPC is 10^-7. I want to know if by changing this value to 10^-7 in test_dvbt2bl_ber_snr_VV, I can obtain the BER value.
