High speed parallel concatenated code coder decoder

The invention discloses a high speed parallel concatenated code coder decoder, which is widely applied to satellite communication systems, deep space communication systems and the like. The high speed parallel concatenated code coder decoder comprises a coder and a decoder, wherein the coder comprises a branch convertor, a first remote sensing (RS) coder, a second RS coder, a third RS coder, a fourth RS coder, a first frame inserting device, a second frame inserting device, a third frame inserting device, a fourth frame inserting device, a first interleaver group, a second interleaver group, a third interleaver group, a fourth interleaver group, a first convolutional code coder, a second convolutional code coder, a third convolutional code coder and a fourth convolutional code coder; and the decoder comprises a phase convertor, a first convolutional code decoder, a second convolutional code decoder, a third convolutional code decoder, a fourth convolutional code decoder, a first frame searching device, a second frame searching device, a third frame searching device, a fourth frame searching device, a first deinterleaver, a second deinterleaver, a third deinterleaver, a fourth deinterleaver, a first RS decoder, a second RS decoder, a third RS decoder and a fourth RS decoder. The coder directly performs concatenated code coding on high speed serial data through a high speed parallel technology, and transmits the coded data to modulation equipment in a parallel mode; and the decoder directly performs concatenated code decoding on parallel data with phase ambiguity output by a demodulator, and problems of sequence randomness of the parallel data, random malalignment of the parallel data and the like caused by the randomness of analog/digital (AD) sampling time can be solved.
