Claim:
A communication system comprising a first communication station and a second communication station, wherein the first communication station comprises: a transmitter configured to convert value information into a code value based on relationship information where plural sets of value information are associated with code values such that a difference between first value information corresponding to a first code value and second value information corresponding to a second code value obtained as a result of an error in one bit of the first code value becomes greater than or equal to two, and transmit the code value converted from the value information to the second communication station, and wherein the second communication station comprises: a receiver configured to receive the code value from the first communication station, and a detector configured to determine that an error has occurred in the code value received from the first communication station when a difference between value information corresponding to a code value received previously and the value information corresponding to the code value received presently is greater than a predetermined value which is equal to or greater than two.
