CDMAchannel
- 语音编码为信源编码，是将模拟信号转变为数字信号，然后在信道中传输。在数字移动通信中，语音编码技术具有相当关键的作用，高质量低速率的话音编码技术与高效率数字调制技术相结合，可以为数字移动网提供高于模拟移动网的系统容量。目前，国际上语音编码技术的研究方向有两个：降低话音编码速率和提高话音质。-Speech coding for source coding is the analog signal into a digital signal, and then in the channel trans

- POCSAG码具有编码效率高、纠错能力强、地址容量大等优点，因此在无线寻呼系统中得到广泛应用。1982年国际无线电通信咨询委员会（CCIR）将其定为“一号无线寻呼码”，又称“国际一号码”。我国亦将其做为公众无线寻呼的标准码。-The POCSAG code has the advantages of high coding efficiency, error correction ability, address large capacity, so it has been widely use
MIMO-performance
- MU-MIMO is widely considered a key technology for system capacity improvement in modern wireless networks. In contrast to SU-MIMO, where the spatial multiplexing gain is confined to a single user, MU-MIMO allows multiple users to be co-sche
