<P>PROBLEM TO BE SOLVED: To realize symbol detection with reliability, by solving a problem of taking-in of two Nyquist points or no Nyquist point in one buffer memory in a conventional way. <P>SOLUTION: While a necessary number of sampling data are sequentially taken in two or more sampling data buffers in the symbol detecting device, the sampling data are delayed by several symbols and taken in a clock reproducing data buffer. To compensate dislocation of a Nyquist point after detecting the Nyquist point from the center of the clock reproducing data buffer, one Nyquist point should be located surely at the center of the buffer memory in the clock reproduction data buffer in constitution or under control, by controlling at least one of the data taking-in and reading-out into the sampling data buffer, the data taking-in in the clock reproduction buffer, and the taking-in/reading-out data length. <P>COPYRIGHT: (C)2007,JPO&INPIT |
