    • Apparatus and method for decoding a Space-Time Block Coded (STBC) signal. The decoding apparatus includes a channel estimator for estimating a real equivalent channel based on a coded signal; a channel converter for decomposing the real equivalent channel to a unit matrix and a subchannel; a receive signal converter for converting the coded signal to a real equivalent receive signal and converting the real equivalent receive signal to a converted receive signal based on the unit matrix; and a detector for detecting an estimate of a transmit signal by performing a maximum likelihood decoding using the converted receive signal and the subchannel. Since the transmit signal candidates are independent of each other, the complexity of the maximum likelihood decoding can be decreased. With the lowered complexity of the receiver, the power consumption for the decoding can be reduced and the high-speed data can be transmitted more easily in the actual mobile communication environment.
    • 用于解码空时块编码(STBC)信号的装置和方法。 解码装置包括用于基于编码信号估计实际等效信道的信道估计器; 用于将实际等效信道分解为单位矩阵和子信道的信道转换器; 接收信号转换器,用于将编码信号转换为实际等效接收信号,并且基于单位矩阵将实际等效接收信号转换为转换的接收信号; 以及检测器,用于通过使用转换的接收信号和子信道执行最大似然解码来检测发射信号的估计。 由于发送信号候选是彼此独立的,所以可以减小最大似然解码的复杂度。 随着接收机的复杂性降低,可以减少解码的功耗,并且可以在实际的移动通信环境中更容易地发送高速数据。
