Parallel channel encoding apparatus applicable in multimedia sensor network

The invention discloses a parallel channel coding device applied to a wireless multimedia sensor network, which comprises a serial-parallel converter, a parallel convolution encoder, a puncher and a parallel interleaver. The device of the invention divides serial data into two rows of parallel data and carries out channel coding operation; compared with the traditional channel coding devices, the channel coding device of the invention doubles the throughput efficiency of data by the mode of slightly doubling the storage space of a shift register in the convolution encoder under the condition of the same working clock; under the condition of the same data rate, the working clock of the channel coding device of the invention can be halved and the working consumption of the channel coding device of the invention is only 1/4 of that of traditional channel coding devices according to the consumption calculation formula of integrated circuits, thereby effectively relieving the problem of energy constraint of wireless multimedia sensor networks.
