    • PURPOSE: An apparatus for making soft decision is provided to stabilize a system by eliminating a division operation from the process of soft decision making and reducing receiver complexity. CONSTITUTION: A channel decoder comprises a symbol demapper(230) and a quantizer(260). A complex soft decision making unit(220) generates a complex soft decision value. The apparatus for soft decision making includes the apparatus for making a complex soft decision which unites the role of a soft decision part with an equalizer and generates the complex soft decision value. A signal passing the quantizer is delivered to a channel decoder(270). A calculating process is operated with a channel element in the symbol demapper and the quantizer.
    • 目的:提供一种用于进行软判决的设备,通过消除软判决过程中的分割操作并降低接收机复杂度来稳定系统。 构成:信道解码器包括符号解映射器(230)和量化器(260)。 复杂的软判决单元(220)产生复杂的软判决值。 用于软判决的装置包括用于进行复杂软判决的装置,其将软决策部分的作用与均衡器相结合,并产生复杂的软判决值。 通过量化器的信号被传送到信道解码器(270)。 利用符号解映射器和量化器中的信道元素来操作计算处理。
