Radio transmitter apparatus, radio receiver apparatus, and wireless communication system
Abstract:
A wireless communication system capable of obtaining diversity gain without fail even when the distribution of the reception qualities is large. In a radio transmitter apparatus (100) of the wireless communication system, a repetition/constellation pattern ratio deciding part (113) adjusts the number of constellations to be used by a modulating part (102) and also adjusts the number of replicas of a repetition part (103) in such a manner that the product of the number of constellation patterns to be used by the modulating part (102), that is, the number of outbound symbols to be generated and the number of outbound symbols as replicated by the repetition part (103) becomes equal to the number of outbound symbols generated from a single transmission data notified from a control information extracting part (112).
Abstract(Chinese):

即使在接收质量的分布大的情况下，能够无失败地获得分集增益的无线通信系统。 在无线通信系统的无线发送装置（100）中，重复/星座图案比例判定部（113）调整由调制部（102）使用的星座数，并且调整重复次数 部分（103），使得由调制部分（102）使用的星座图案的数量的乘积，即要产生的出站符号的数量和由重复的复制的出站符号的数量的乘积 部分（103）变得等于从从控制信息提取部分（112）通知的单个发送数据产生的出站符号数。
