Question

Reconsider the spread-spectrum in Example 5.1 where the received code delay uncertainty is ±11.157μs. The system is subjected to code Doppler of 4 kc/s. Calculate each of the following:

i. mean acquisition time without code Doppler
ii. mean acquisition time with code Doppler
iii. variance of the acquisition time without code Doppler
iv. variance of the acquisition time with code Doppler.
