A communication system capable of avoiding crosstalk with a simple structure. By assigning the same identification-number data to a transmitter and a receiver, performing the logical operation for the identification-number data with the logical operation circuit of the transmitter and the receiver, and detecting errors in the operation results by using error detection circuit, it is possible to perform enciphering and certifying without increasing communications traffic and thus avoid crosstalk with a simple structure because it is unnecessary to add and transmit the identification-number data.

DETAILED DESCRIPTION In view of the foregoing, an object of this invention is to provide a transmitter, a receiver, and a communication system and communication method capable of avoiding crosstalk with a simple structure.
The foregoing object and other objects of the invention have been achieved by the provision of a transmitter for transmitting input data after applying predetermined data processing to the input data.
The transmitter comprises: error-detection-code addition means for adding an error detection code to the input data; logical operation means for generating transmission data by applying the logical operation between the output data output from the error-detection-code addition means and the identification-number data assigned to the transmitter to the transmission data; and transmission means for transmitting the transmission data after applying predetermined transmission processing to the transmission data.
Further, this invention provides a receiver for receiving a transmission signal transmitted from a transmitter.
The receiver comprises: reception means for receiving the transmission signal; logical operation means for performing the logical operation between the reception data received by the reception means and the identification-number data assigned to the receiver; and error detection means for detecting an error in the output data in accordance with an error detection code added to the output data output from the logical operation means and disusing the output data when the error is detected.
Further, this invention provides a communication system for performing communication between a transmitter and a receiver.
In the communication system, the transmitter has error-detection-code addition means for adding an error detection code to input data, first logical operation means for generating transmission data by performing the logical operation between the first output data output from the error-detection-code addition means and the first identification-number data assigned to the transmitter, and transmission means for transmitting a transmission signal generated by applying predetermined transmission processing to the transmission data
