BACKGROUND OF THE INVENTION In the existing UMTS system, due to the large interference of neighboring cells, the theoretical limit capacity of a single cell and the capacity of an actual networking are greatly different. With the increasing interest in spectrum utilization efficiency of UMTS technology, more wireless communication technologies use higher order modulation to increase downstream capacity, and these higher order modulations have a limited range of uses. Figure 1 shows three higher-order modulation techniques, which are divided into R99, 16QAM (Quadrature Amplitude Modulation), and 64QAJVL. See Figure 1. In the current UMTS system, due to the interference of neighboring cells, As a result, the area capable of providing high-order modulation is far away from the coverage area, so that in the actual networking, the capacity of the cell cannot reach the theoretical capacity of the system. It can be seen that the coverage areas of these three technologies are quite limited. Taking the HSDPA (High Speed Downlink Packet Access) networking as an example, in the case of 3/4 encoding, the cell can provide 10.8 Mbps/cell downlink traffic, but in the design group. The average rate in the network can only reach 1.8Mbps/cell, and the utilization rate has not reached 20% of the theoretical value. With the enhancement of 3G data providing capabilities, operators hope to provide a wireless means of competing with DSL. Wireless DSL access is used in each user's home. There are UMTS-WiFi devices in front of the ID, but these devices are placed in the user. In the home, the wireless environment is complex, there is neighboring area interference and multipath interference, which causes the downlink capacity to drop, so the spectrum utilization rate is not high. Therefore, there is a need for a new UMTS-based DSL access system and method that solves the problems in the related art described above. SUMMARY OF THE INVENTION The present invention is directed to providing a new UMTS-based DSL access system and method, so as to solve the problem that the actual networking capacity of the original UMTS networking cannot meet the theoretical limit capacity well, so the wireless device cannot be provided well. DSL access and other issues.
