    while evaluating the Bit Error Rate in a fading channel we equalize the received bits before demodulating. so we multiply with the pseudo inverse of the channel matrix.
    what will be the pseudo inverse of a rank 1 matrix ie rank deficient matrix ?
    I am evaluating BER for BPSK in a keyhole MIMO channel.

  2. The pseudo-inverse of a rank 1 matrix is well defined.
    It is also rank 1 of course.

    I'm not sure what you are asking though. Do you
    wish to know how to compute it? Pinv does the work
    for you, although it is quite easy to do on your own.
