Abstract—Mobile devices performing video coding and
streaming over wireless and pervasive communication networks
are limited in energy supply. To prolong the operational lifetime of
these devices, an embedded video encoding system should be able
to adjust its computational complexity and energy consumption
as demanded by the situation and its environment.
This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).
