Network coding cooperation technology based on QC-LDPC code
LI Wanche · 2013
In order to overcome the limitations of traditional collaboration technologies,this paper proposes a network coding cooperative communication technology based on QC-LDPC code,which combines the Alamouti orthogonal space-time codes,network coding technology and coding cooperation technology(coding cooperation based on QC-LDPC code).The simulation results show that under the condition of keeping system bandwidth and transmission power invariant,this scheme can overcome the radio channel fading and get better coding gain and diversity gain under the higher spectrum utilization efficiency and lower hardware cost conditions.
