Kazkou,
Assuming that the question is how to determine the value of the loop bandwidth, equation #11. The values in the equation are the design values of the blocks in the design. So in theory, you should be able to calculate the BER from the initial design studies. The values of Kpd and H(f) should be fixed. The value of Kvco maybe a challenge since control voltage to frequency transfer function maybe non-linear. However, in most cases this relationship is controlled by the VCO calibration and should effectively be a constant also.
