Question:

Assume that the delay in a delay-and-multiply receiver for DPSK as shown in Fig. 9.17 is in error by |Î”T|.

(a) Show that the asymptotic bit error probability becomes E, PE, IAT| N JAT| Ep No = e(VE) + e(vz(1 – |AT| R)

(Consider the possible data sequences 11, 00, 10, and 01 thereby accounting for the cases of degradation and no degradation in the signal component at the integrator output.)

(b) Plot P_E,|Î”T|versus z in dB for |Î”f| R = 0, 0.1, 0.2, 0.3, 0.4. Estimate the degradation in dB at a probability of error of 10^-6.
