A kind of wireless communication technology based on coding and decoding device multi hop convolutional code and its realization method, the device comprises a relay node sending and receiving terminals and the N cascade, the receiving end comprises a hard decision decoder and N and n+1 sub class de interleaver, the sub decoder for the addition of SISO or Viterbi decoder decoding module. In the auxiliary cellular communication system where relay nodes are introduced, a distributed cascade code is formed by utilizing the cascading characteristics of the multi hop path itself, thereby obtaining better error levels than the single hop mode.
