Mobile body communication apparatus

摘要: When communications of the same data are performed using a multi-carrier modulation method between plurality base stations and mobile station at time with frequency, standing wave interference is generated to lower carrier electric field level bit error rate increased if located in an area where reception powers waves from almost identical. In order prevent this, phase differences set sub-carriers so as enable avoid situation which all mutually cancelled. Thus, it possible easily correct error, thereby improving quality communication.
