Assignment:
Input data at 75 bits/s are channel encoded using a rate encoder. The coded bits are then modulated using 8-ary FSK. The FSK symbols are then spread by frequency hopping at a rate of 2000 hops/s.
(a) What is the chip rate?
(b) What is the order of diversity?
(c) If there are two such signals, time-division multiplexed (TDM'd) on the channel at the same hopping rate, how would this affect the chip rate, symbol rate, and order of diversity?
(d) If there are 80 such signals TDM's on the channel, how would this effect the chip rate, symbol rate, and order of diversity?
Provide complete and step by step solution for the question and show calculations and use formulas.
