    Covariance matrix estimation Chan and Ho position estimation method

    Hello, I want to use the Chan and Ho position estimation method described in : "A simple and efficient estimator for hyperbolic location systems", IEEE, VOL 42,NO.8,AUGUST 1994 **broken link removed** I want to use the simplified form of the covariance matrix Q on page 1911, but i cannot...

    What is Pilot ? & What is synchronization in OFDM?

    Hallo , I am a student and I have to estimate the time delay of three OFDM frames sent from three cells (Matlab). My idea is first to find the integer delay during the synchronisation using the P-SYNC and S-SYNC pilots and after that to do a more precisely estimation in the frequency domain...

    What is diffirent between CP and PN in OFDM system for synchronization

    Hi Emily, I am in the same situation like you. I am a student and I have to write a Matlab function for synchronization in OFDM system. I found an interesting book and perhaps it can be useful for you: "MIMO-OFDM Wireless Communications with Matlab", Y.S Cho,J. Kim, W.Y.Yang,Ch Kang, Wiley...

    Timing Estimation with polyfit()

    Hallo everybody, I have to find the time delay of an OFDM frame.I want to find the time delay using Positioning Reference Signals (PRS). Idea: The receiver does the FFT and the frame is in frequency domain. I create a reference frame only with PRS and a logical mask of the reference frame. I...
