Assignment:
Consider an FH/MFSK system such as the one shown in Figure. Let the PN generator be defined by a 20-stage linear feedback shift register with a maximal length sequence. Each state of the register dictates a new center frequency within the hopping band. The minimum step size between center frequencies (hop to hop) is 200 Hz. The register clock rate is 2 kHz. Assume that 8-ary FSK modulation is used and that the data rate is 1.2 kbits/s.
(a) What is the hopping bandwidth?
(b) What is the chip rate?
(c) How many chips are there in each data symbol?
(d) What is the processing gain?
Provide complete and step by step solution for the question and show calculations and use formulas.
