<P>PROBLEM TO BE SOLVED: To provide a receiver circuit capable of detecting the top of data, regardless of whether or not a reception signal contains a preamble or unique word, without depending on coding method of the reception signal. <P>SOLUTION: A receiver circuit 100 includes a correlational calculation part 11 which generates a correlational signal by performing correlational calculation while sliding the reference signal of one symbol to a reception signal. Related to the reference signal, a 1/2 symbol period in first half is at high level while a 1/2 symbol period in second half is at low level. The receiver circuit 100 further includes a delay part 17 which outputs a delay signal in response to the reception signal by delaying by the amount of 1/2 symbol period of the reference signal, and a data top timing detection part 16 which detects a peak timing at the top of the correlation signal as the timing of top of data contained in the delay signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
