<p>The synchronizing apparatus includes a block (102) for detecting a code (103) from an input signal (13), a block (105) for detecting from the code the variable points of the code at several times as high as the symbol rate, a block (107, 108, 1140-114N-1) for calculating a histogram of the detected variables of the code to time, and a block (108, 122) for deciding that the phase number at which the calculated histogram takes the maximum value is a symbol synchronization point. This synchronizing apparatus detects the zero-cross points of an intermediate frequency band signal (103) at N times as high as the symbol rate. It also calculates a histogram of detected time (0 to N-1). The time (0 to N-1) at which the histogram is the maximum within a predetermined detected time is selected as a symbol clock, and thereby symbol synchronization is established.</p> |
