MOBILE BODY COMMUNICATION SYSTEM, MULTI-CARRIER CDMA TRANSMISSION APPARATUS, AND MULTI-CARRIER CDMA RECEPTION APPARATUS

摘要

In a mobile body communication system,a multi−carrier CDMA reception apparatus corrects soft decision data by using an amplitude component of a channel estimation value,performs turbo decoding,selects an encoding ratio according to reliability information of the decoded data,and reports the encoding ratio to a transmission apparatus via an uplink line.A multi−carrier CDMA transmission apparatus performs encoding by using the encoding ratio reported.
