Problems solved by technology

The technical disadvantages based on frequency division multiplexing are: the demand for spectrum is wide, the spectrum is a scarce resource for operators, and the waste of spectrum resources is large
Conversely, based on the technical disadvantages of time-division multiplexing: the demand for spectrum is small, but for the user station, because each transit node must work in time-sharing, the average data communication rate of each transit node is reduced, and the throughput increase of the user station is limited or even possible. Instead lower

Embodiment Construction

[0097] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0098] The present invention uses multiple antennas of multiple transit nodes in the transit wireless access system to form a mutual aid group, and jointly realizes distributed MIMO technology and spatial coding and decoding technology (for example, layered spatial multiplexing code, space-time code, space-frequency code or Combination of space-time-frequency codes), so that the advantages of space division technologies such as MIMO can be fully utilized on the basis of existing equipment conditions and used in such a frontier field as broadband wireless access. Through the use of MIMO space division technology to realize the technology of multiple transit nodes accessing the same destination node, it supports user stations to simultaneously access the same base st...

Abstract

This invention relates to one wide band wireless interface system and discloses one transfer system and its method to improve the spectrum materials utility, wireless signal capacitor and data communication speed, which firstly using OFDM technique to change the frequency selective channel into flat anneal channel to form antenna MIMO system by use of one set transfer points antenna to realize one set of mutual distribution MIMO code transmission system.

Description

technical field [0001] The invention relates to a broadband wireless access system, in particular to a transfer system and method for broadband wireless access. Background technique [0002] In recent years, the broadband wireless access technology has attracted widespread attention. Compared with other broadband access technologies, the broadband wireless access system has many advantages, such as low investment, short construction period, and fast service provision. The International Institute of Electrical and Electronic Engineers (Institute of Electrical and Electronic Engineers, referred to as "IEEE") committee specially formulated the IEEE802.16 standard to propose a broadband wireless access solution, but it must ensure line-of-sight transmission. For densely populated cities, due to There are many obstacles such as tall buildings and trees, resulting in very limited coverage. Therefore, in the IEEE802.16a standard formulated later, a broadband wireless access solutio...
