Abstract :
A point-to-point communication system with an AWGN channel is considered. It is assumed that data randomly arrive at the system and the transmitter has a finite buffer. Supposing that, to save energy, the transmitter is able to adapt the rate depending on the number of bits existing in the buffer, the stationary probability distribution of the number of bits in the buffer is obtained and an approximate relation for the average of saving in energy is found.
