Hi Johannes, First of all thanks for the quick response and time with my problem. I've made a text file with all specifications of my OFDM example that can be found in the attachments of this mail. Thanks again with your help and anything more just let me know. Best regards, Pedro Viegas

Hi Pedro, we'd need more info to tell why you observe these peaks. How large are your input packets? Do they span multiple OFDM symbols? How many subcarriers are active? Your peaks hint at some kind of repetition or lot's of zeros. Cheers Johannes On 14.12.21 13:07, Pedro Viegas wrote:
