Assignment:
Spread-spectrum techniques can be used to meet government regulations regarding flux (power) density radiating the surface of the earth. If a satellite at synchronous altitude (36,000 km) transmit 4-kbits/s data using 100 W of EIRP. what spreading bandwidth is required to maintain a flux density on the earth's surface no greater than —151 dBW/m2 in any 4-kHz band?
Provide complete and step by step solution for the question and show calculations and use formulas.
