<P>PROBLEM TO BE SOLVED: To provide a technology that makes it possible to improve a packet catch rate, for example, in the case of being applied to a communication device. <P>SOLUTION: An SNR improvement circuit 4 improving an SNR of an input signal includes: a delay part 50 generating one or more delay signals by delaying the input signal; and an addition part 60 adding the one or more delay signals and the input signal before being delayed. The input signal includes periodic signals generated by repeating the same signal predetermined times at a predetermined cycle. The delay part 50 generates the one or more delay signals by using delay time that is an α-fold time of the predetermined cycle, where α is a natural number and is set at a value differing from each other for two or more delayed signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
