Abstract: PURPOSE: A device for channelizing signals in a mobile communication terminal system is provided to process an IF(Intermediate Frequency) band signal by a digital method, so as to simply form an analog element to perform a low-power consume. CONSTITUTION: In a receiver(220), an A/D converter is located in a fore most terminal, and converts multi carrier waves which are band filtered into digital signals. In a transmitter, a D/A converter is located in a rearmost of a signal processing terminal, and converts digital signals from a modem(260) into analog signals. A channelizing structure samples signals of a 5MHZ bandwidth to convert the signals into digital signals, and multiplies NCO(Numerically-Controlled Oscillator) output signals corresponding to each carrier frequency by the converted digital signals, to lower the multiplied signals to a baseband. The signals of the lowered baseband are separated from adjacent channel signals through an LPF(Low Pass Filter) and a digital filter, and are transmitted to the modem(260) to perform corresponding signal processes.
Abstract translation: 目的:提供一种用于在移动通信终端系统中信道化信号的装置,以通过数字方式处理IF(中频)频带信号,以简单地形成模拟元件来执行低功耗。 构成:在接收机(220)中,A / D转换器位于最前端,并将被频带滤波的多载波转换为数字信号。 在发射机中,D / A转换器位于信号处理终端的最后端,并将来自调制解调器(260)的数字信号转换为模拟信号。 通道化结构采样5MHZ带宽的信号将信号转换为数字信号,并将与每个载波频率相对应的NCO(数控振荡器)输出信号乘以转换后的数字信号,将乘法信号降低为基带。 降低基带的信号通过LPF(低通滤波器)和数字滤波器与相邻信道信号分离,并被发送到调制解调器(260)以执行相应的信号处理。
