Filed: 2003-04-03
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a decoder side from being incapable of carrying out decoding because the decoder side cannot accurately detect a frame synchronizing signal due to an interference between codes in the case of obtaining a transmission bit sequence by inserting a particular bit pattern equivalent to the frame synchronizing signal to a code bit sequence resulting from coding an information bit sequence with a concatenated convolutional code by each frame.  <P>SOLUTION: The particular bit pattern adopts a bit configuration having a minimum bit inversion interval being an integer multiple, 2 or over, of a minimum bit inversion interval of a code bit sequence. The decoder side is not susceptible to the effect of an inter-code interference and can surely detect the frame synchronizing signal by using the particular bit pattern satisfying a condition for the frame synchronizing signal. Further, noise immunity is improved and this technology is suitable for a transmission path environment wherein the concatenated convolutional code is in use.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
