New Technology for New Generation TelecomA new technology, the LAS-CDMA technology and I-schematic device, which is developed on the basis of China's independent intellectual property, recently passed the formal test by the Ministry of Information Industry.The technology, which is invented by Prof. Li Daoben, chief scientist of a telecom technology company limited in Beijing, effectively overcomes the serious defects of the existing CDMA, such as being subjected to the interference of multiple address, inter-coding and neighboring area by its unique characteristics of "interference-free window". The frequency spectrum efficiency realized by the technology is six times higher than that of the existing CDMA. It is compatible with the current wireless communication standard, and is meeting the requirement of future IP network development as well, thereby giving a great fillip to the upgrading of telecommunication products as well as the sustaining enlargement of telecom service. The great innovation of CDMA technology has been confirmed as one of the three international standards juxtaposed with the program put forward by Motorola and another company at the International Conference of 3GPP2 of CDMA. Currently the development of the practical system of this new technology is advancing at full speed. |
