Hello I am Takuya Nakanishi. I am a 4th year college student from Japan. I have two questions.I want to send OFDM preamble signal.and I created blocks are random source,OFDM mod,OFDM insert preamble and usrp sink in a program. But, I don't understand OFDM insert preamble block's parameters"Preamble and FFT Length". Q1: What does two parameters indicate? Q2: "In the attachment" OFDM insert preamble block's flags. I'm sorry.I weak English. Regards.
