另外，时分双工是一种通信系统的双工方式，在移动通信系统中用于分离接收和传送信道。移动通信目前正向第三代发展，中国于1997年6月提交了第三代移动通信标准草案(TD-SCDMA)，其TDD模式及智能天线新技术等特色受到高度评价并成三个主要候选标准之一。在第一代和第二代移动通信系统中FDD模式一统天下，TDD模式没有引起重视。但由于新业务的需要和新技术的发展，以及TDD模式的许多优势，TDD模式将日益受到重视。In addition, time division duplexing is a duplexing method of a communication system, and is used in a mobile communication system to separate reception and transmission channels. Mobile communication is currently developing into the third generation. China submitted the draft third-generation mobile communication standard (TD-SCDMA) in June 1997, and its TDD mode and new smart antenna features were highly praised and became three main candidates. one of the standards. In the first and second generation mobile communication systems, the FDD mode dominates the world, and the TDD mode has not attracted much attention. However, due to the needs of new services and the development of new technologies, as well as the many advantages of the TDD model, the TDD model will receive increasing attention.
时分双工的工作原理如下：TDD是一种通信系统的双工方式，在移动通信系统中用于分离接收与传送信道(或上下行链路)。TDD模式的移动通信系统中接收和传送是在同一频率信道即载波的不同时隙，用保证时间来分离接收与传送信道；而FDD模式的移动通信系统的接收和传送是在分离的两个对称频率信道上，用保证频段来分离接收与传送信道。The working principle of time division duplex is as follows: TDD is a duplex mode of a communication system, which is used to separate reception and transmission channels (or uplink and downlink) in a mobile communication system. In the mobile communication system of TDD mode, the reception and transmission are in the same frequency channel, that is, different time slots of the carrier, and the reception and transmission channels are separated by guaranteed time; while the reception and transmission of the mobile communication system of FDD mode are separated by two symmetrical On the frequency channel, the guaranteed frequency band is used to separate the receive and transmit channels.
采用不同双工模式的移动通信系统特点与通信效益是不同的。TDD模式的移动通信系统中上下行信道用同样的频率，因而具有上下行信道的互惠性，这给TDD模式的移动通信系统带来许多优势。The characteristics and communication benefits of mobile communication systems using different duplex modes are different. In the mobile communication system of the TDD mode, the uplink and downlink channels use the same frequency, so there is reciprocity of the uplink and downlink channels, which brings many advantages to the mobile communication system of the TDD mode.
在TDD模式中，上行链路和下行链路中信息的传输可以在同一载波频率上进行，即上行链路中信息的传输和下行链路中信息的传输是在同一载波上通过时分实现的。In TDD mode, the transmission of information in the uplink and downlink can be performed on the same carrier frequency, that is, the transmission of information in the uplink and the transmission of information in the downlink are realized by time division on the same carrier.
