Assignment:
A ground-to-synchronous satellite link must be closed in a jamming environment. The data rate is 1 kbit/s and the ground station has a 60-ft antenna. Antijam protection is provided by a 10-Mbits/s direct-sequence spread-spectrum code. The jammer has a 150-ft antenna and a transmitter with 400 kW of power. Assume equal space and prop-agation losses. How much power is required of the earth station transmitter to achieve an E,,/Jo of 16 dB at the satellite receiver? Assume that the receiver noise is negligible.
Provide complete and step by step solution for the question and show calculations and use formulas.
