Question: Write a computer program to evaluate the degradation imposed by bit timing error at a desired error probability as discussed in Problem 9.7. Data From
Data From Problem 9.7.
The received signal in a digital base band system is either +A or -A, equally likely, for T-second contiguous intervals. However, the timing is off at the receiver so that the integration starts ÎT seconds late (positive) or early (negative). Assume that the timing error is less than one signaling interval. By assuming a zero threshold and considering two successive intervals [i.e., (+A, +A), (+A, -A), (-A, +A), and (-A, -A)] obtain an expression for the probability of error as a function of ÎT. Show that it is
Plot curves of PE versus Eb / N0 in dB for |ÎT|/T = 0, 0.1, 0.2, and 0.3 (four curves). Estimate the degradation in Eb / N0 in dB at PE = 10-4 imposed by timing misalignment.
