PROBLEM TO BE SOLVED: To allow a receiver which is not a communication opposite party of a transmitter to decrease a time required for discriminating a different identification code in a communication method, where the transmitter repetitively transmits a connection signal including the identification code. SOLUTION: In this communication method, when a connection signal is repeatedly transmitted, an identification code extract means 9 extracts a partial identification code different every time, in response to the number of times of transmission from an identification code of a communication opposite party and inserts the partial identification code, together with the number of times of transmission to a transmission text. At reception, a position specific code detection means 11 discriminates the number of times of transmission from a control code in the received connection signal and outputs it to a partial identification code comparison means 12. The partial identification code comparison means 12 uses the number of times of transmission to compare the partial identification code, in the received connection signal with own identification code. |
