    • PURPOSE: An open loop antenna selecting apparatus using an Indication bit and modulation and a method thereof are provided to restore a transmission signal of a multi-antenna transmission device as it is by selecting a transmission antenna with good channel state through deciding whether a data bit about a receiving symbol satisfies the Indication bit. CONSTITUTION: An indication bit extractor(101) extracts an Indication bit for selection of a transmission antenna with a use of the bit. The bit is allocated in an input symbol. A modulation unit(103) modulates a remaining bit except for a lower bit among an allocated bit. A transmission antenna switching unit(105) creates a transmission antenna index through the lower bit and the Indication bit. The transmission antenna switching unit proceeds switching to the transmission antenna corresponding to the transmission antenna index.
    • 目的:提供一种使用指示位和调制的开环天线选择装置及其方法,用于通过选择具有良好信道状态的发送天线来决定数据比特是否被复原,来恢复多天线发送装置的发送信号 关于接收符号满足指示位。 构成:指示位提取器(101)使用位提取用于选择发送天线的指示位。 该位在输入符号中分配。 一个调制单元(103)调制一个分配的比特以外的低位的剩余比特。 发送天线切换单元(105)通过低位和指示位产生发送天线索引。 发送天线切换单元对与发送天线指标对应的发送天线进行切换。
