Er, no. This is the number of bytes per packet. It's 96 because we add 4 bytes for CRC, and then the packet number is a round value. At 100 bytes per packet, the payload is 800 bits. With BPSK, that would be 17 OFDM symbols (plus 1 OFDM symbol for header, and 2 for preamble). You can set whatever here, but remember that the stock equalizers don't do a good job on long packets. Also, the length can vary per packet. > - The number of total carriers in the systems equals the FFT length. > In this case, 48 data carriers and 4 pilots, 52 total and the rest are set > to 0. This is correct (compare 802.11a standard). M _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
