Abstract :
Spatial division multiple access (SDMA) wireless communication systems, where multiple user signals are simultaneously transmitted and received over same conventional time/frequency channels by using multiple antennas, have great potential to dramatically increase spectral efficiency. The iBurst, a TDD-TDMA based mobile broadband wireless Internet network, is the first commercial system in the world to realize and demonstrate the potential benefits of SDMA technology with the help of adaptive array antenna (AAA) processing. This paper presents and discusses the structure of the iBurst system, its antenna array configuration, system specifications, and field performance test results. Next, by adding OFDMA transmission technique to this multiple antennas system, the simulated performance results of beamforming are presented.
