Inventor: YOKOYAMA AKIHISA
IPC: H04L27/38
Filed: 2003-06-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a symbol synchronization method for a quadrature modulation signal capable of avoiding clock slip even when bit duplication or bit missing happen due to clock jitter or the like in the case of sampling an Ich signal and a Qch signal, in symbol synchronization for demodulating an input quadrature modulation signal.  <P>SOLUTION: In the case of sampling the Ich signal and the Qch signal recorded in a sampling data recording section 20, when an optimum timing position in a frame ri changes from 0 to n (bit missing), the optimum timing position in the frame ri can be corrected from n to '0 and n'. When the optimum timing position in the frame ri changes from n to 0 (bit missing), the optimum timing position in the frame ri can be corrected from 0 to 'none'. That is, the bit missing or bit duplication in the frame ri can be corrected by changing the frame length.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
