Document Summary
All questions are of equal value (with part marks indi- cated) but not necessarily of equal di culty. Full marks shall only be given to solutions that are properly explained and justi ed: (class2k modulation) figure 1-(a) plots the 4 signals used in miller modulation. Note that each signal has an energy of eb = v 2tb. Figure 1-(b) shows the state diagram of miller modulation, which tells us how a transmitted signal is generated based on the current input bit and the modulator"s state. The error probability of the symbol- by-symbol demodulation of miller signaling was derived (in the text and class) to be approximately 2q(cid:16)q eb. N0(cid:17), where as usual n0/2 is two-sided power spectral density of. The factor of 2 in the above expression arises from the fact that each bit has. To address this your friend suggests a modi ed state diagram in figure 1-(c), which shall be called class2k (class of 2000) modulation.
