Abstract:

To solve the signal the whole bring to the emission of electromagnetic pollution and interfere with each other,a new multiple access smart antenna systems.On the basis of the multiple access technology, the introduction of the SDMA(space-division multiple access) system model,and space division multiple access system to carry out a more detailed and comprehensive analysis. The SDMA combined with the traditional multiple access, analyze the application.The computer simulation results show that the simulation and theoretical consistency.

Key words: multiple-access technique, space-division multiple access(SDMA), basestation;multiple beams;array cell, spread-frequency code
