    Plan: just a few more minutes to understand the zero force equalizer
    Result: mmse equalizer just compares signals. zero force inverts frequency response in order to find the optimal weights (only one 1, rest 0s) that minimize ISI

    finished 30m timer
    Plan: continuing to learn about the equalizer
    Result: didn't realize that zero force equalizer is not the minimum least squares equalizer, so im looking that up and trying to understand the optimization variables

    Plan: looking through conference papers
    Result: went through about 7 minutes of a tutorial (to 36 min) and got stuck at the equalizer

    Plan: trying to understand the particular solution, and how he got the null space, and why that's relevant. might look for a book.
    Result: there is a theorem that i found in the notes that helps. moving on for today.

    Plan: look over conference papers and summarize here
    Result: QKD demo about netwk archtr not QDK; not sure what network streaming is for OPM of networks; phase retrieval relying on algorithms-not hardware; gotta go2class!

    Plan: MMSE filter and biased estimators
    Result: I have a rough idea of both. Not sure exactly how MMSE filter relates to Weiner filter. Remembered more about estimators. last 5 min spent reviewing bike route
  • Avatar for heidi
    finished 30m timer
    Plan: looking up terms i dont know very well from the course notes. will list what i learned here.
    Result: mainly went through what filters were. also the Wiener Kintchin theorem. Heard about (un)biased estimators, but I still dont know what they mean. coffee now

    Plan: reading this: www.stat.ucla.edu/~frederic/415/F18/ch4.pdf sections 4.2 and 4.3
    Result: I meant to say 4.1 and 4.2. I got what i needed out of the book - that the PSD is Fourier Trm of the autocovariance, and that PSD shows variances in freq domain
