Partial network coding with cooperation : a study over multi-hop communications in wireless networks

Creator:: Poocharoen, Panupat
Abstract:: The imperfections of the propagation channel due to channel fading and the self-generated noise from the RF front-end of the receiver cause errors in the received signal in electronic communication systems. When network coding is applied, more errors occur because of error propagation due to the inexact decoding process. In...
