Abstract:Distributed source coding is a new hot spot in the wireless sensor network area. This paper introduces the fundamental theory of dis- tributed coding,then LDPC coding and multilevel coding methods applied in distributed coding are given. Finally, a distributed multilevel coding method is proposed to realize correlated M-ary sources coding and in the case of different correlation between two sources the performances of distributed correlated M-ary sources coding are compared.
Keywords:LDPC
