  1. A Frequency Hopping Spread Spectrum (FHSS) system employs a total bandwidth of Ws = 400 MHz and an individual channel bandwidth of 100Hz. What is the minimum number of PN bits required for each frequency hop.

  2. A FHSS system uses M-FSK. The data to be transmitted and the PN sequence are given below. If the data rate is 3 Kbps and the Baud Rate is 1Ksymb/s; and the PN sequence bit rate is 2 Kbps with a hop occurring every 2 bits. a) What is the duration of a single bit. c) What is the duration of a single symbol d) What type of MFSK is being used (value of M) e) How many different frequencies are going to be used

  3. Draw the complete FHSS distribution (t/f diagram using the table provided) DATA: 001110111111110010000011101101110111 PN: 011011011000001011011011

  4. A communications system is using FHSS to transmit a bitstream. The bit-rate is twice the PN sequence rate. If the bit-rate is 4 kbps, and the received sequence of frequencies is • Find the PN sequence rate b) Find the bit-stream if the it is being transmitted using 16-FSK with a jump in frequency occurring every 1 ms. (note that the frequencies start with f0,, and this frequency is used to transmit a data symbol equivalent to 0 when the PN symbol is also 0. (12 marks)
