Assignment:
A coherent DS/BPSK system is transmitting at a data rate of 10 kbits/s in the presence of a broadband jammer. Assume that the system does not use channel coding. Also assume that the propagation losses are the same for the system and the jammer.
(a) If the EIRP of the communicator is 20 kW and the EIRP of the jammer is 60 kW, calculate the required spread-spectrum bandwidth to achieve a bit error probability of PB =10-5.
(b) If the jammer is a pulse jammer, calculate the pulse duty cycle that results in worst-case jamming. What is the value of PB at this duty cycle?
Provide complete and step by step solution for the question and show calculations and use formulas.
