  9. 2.Smart Antennas

  10. Smart antennas for base station Normal Antenna Beam pattern AAA Beam pattern Adaptive Array Antenna(AAA) Desired user High-rate user Calculate optimum beam pattern in realtime Desired signal Interference Interferer Interferer

  11. Effects of AAA（System Capacity） The up-link characteristics are dominant in connection with the number of voice users and cell radius. Uplink: With the same number of channels, implementation of the 8-element AAA increases the cell radius by twice (the coverage by 4 times) compared with the 2-antenna RX-Div. Up/downlink: For a certain cell radius (1 km), the number of voice users increase in proportion to the number of antenna elements. 8ele_AAA_dl 8ele_AAA_up 4 4 6ele_AAA_up 6ele_AAA_dl 4ele_AAA_up 4ele_AAA_dl 2ant_RX_Div 2ant_TX_Div 3 3 Cell radius [km] 2 2 Cell radius [km] セル半径 [km] セル半径 [km] 1 1 0 0 0 200 400 600 800 1000 1200 1400 0 200 400 600 800 1000 1200 1400 user [ch/carrier/cell] user [ch/carrier/cell] Number of voice users in uplink and cell radius Number of voice users in downlink and cell radius

  12. Effects of AAA (Expansion of cell coverage for uplink) The higher the user density, the greater the coverage expansion thanks to the interference elimination effect of the AAA. 5 User density=10 ch/km2 User density=40 ch/km2 User density=160 ch/km2 4 AAA cell coverage for 2RX-Div [Times] 2RX-Divに対するAAAセルカバレッジ[倍] 3 2 1 3 4 5 6 7 8 9 Number of AAA (Unit) AAAのアンテナ数 [本]
