Dear all, I finally figure out how to receive packet using OFDM and Alamouti but unfortunately looks like I cannot detect all the peaks. 10% of the packets that I receive are right. I think that I experience a phase rotation, i.e. instead of receiving -1, I receive +1 for some preamble symbols and hence the channel estimate matrix has negative components. I am using PN to detect peaks.
Do you have any advise or suggestion on how to fix this? I though to put a delay using a sleep in the alamouti encoder between 2 consecutive OFDM symbols in order to avoid the overlapping of symbols but it doesn't work. Looking forward to hearing from you Vanessa _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
