Satellite communication channel has the characteristic of power limited, band abundance, and powerful error correcting ability FEC scheme is needed.
卫星通信信道具有功率受限、带宽充足的特点，要求采用具有强大纠错能力的信道纠错技术。
These modules were comprised of the realization of FEC and the decode of Viterbi, the shape of base-band wave, FFT and so on.
这些关键模块包括基带系统中的差错控制编码和维特比译码，成形滤波，FFT变换等。
