频隙 meaning in Chinese
frequency slot
Examples
- Frequency slot interchange fsi
频隙交换 - Cdma has become the main technology of the third generation mobiletelecommunication . many users in cdma system are distinguished by differentspread sequences and have the same time chip and frequency unlike in theconventional tdma system or fdma system . but the practical spread sequences cannot reach the ideal condition , the correlation function equals zero , so that it will causethe multiple access interference ( mai ) when lots of people are communicating . multi - user detection ( mud ) makes joint detection on the received signals by makingfull use of the information of all users ’ , which relaxes mai and increases the capacityof system
Cdma技术已经成为第三代移动通信系统中的主流技术,它与传统的fdma 、 tdma不同,在cdma系统中多个用户均占用同一时隙、同一频隙,所不同的是选取的地址码不同,而实际选用的地址码间的互相关函数又不可能全部达到理想状态的全为零,因而造成了多个用户同时通信时,必然要产生多址干扰。
