Time PN Sequence 2. (20 points) The following table illustrates the operation of an FHSS system for one complete period of the PNsequence- r , T e 9 T 10 11 001 110 011 Frequency fl 0 f3 23 122 18 fio Time PN Sequence Input Data Frequency 12 13 1415 16 17 18 19 001 001 fl f3 f2 a) The system makes use of a form of FSK. What form of FSK is it? b) What is the number of data bits represented by one signal symbol? c) What is the length of a PN sequence per hop? d) Is this a slow or a fast FH system? e) What is the total number of possible carrier frequencies?Explanation / Answer
(a) The form of FSK system used is MFSK( M -ary FSK or Multiple FSK).
?(b). The number of data bits per signal element is L= 2( Refer to any of the frequency hop given in the question).
?(c). The length of PN sequence per hop is k=3.
?(d.) Here multiple signals per hop; Tc>Ts .Therefore its a slow FH system(Slow FHSS)
?(e). The possible number of carrier frequencies= 2^k=2^3=8.
