- W2389596907 abstract "The carrier phase-shift directional beamforming scheme is widely employed in smart antenna(SA) system.However,the disadvantage of the phase shifter scheme is that it can not make full use of the technology of base-band signal processing and its complexity in engineering implementation.According to the study of the basic principle of SA directional beamforming,the mathematical model of SA directional beamforming realized on base-band is obtained firstly.With the mathematical model,the concept of base-band amplitude weighting beamforming(BAWB) is proposed as well as the corresponding circuit implementation unit.Based on the presented BAWB scheme,the beamforming performance analysis in CDMA system,where multiple code channels are transmitted simultaneously,is performed.The results of numerical analysis show that,due to the interaction among different code channels with different directions and the impact of strong side lobe on major lobe,the resolution of major lobe is greatly decreased.The situation is worse when the data of different code channels change fastly.At the same time,the dialectical relationship between the multi-access interference(MAI) and the system performance in CDMA is also discovered.On one hand the MAI limits the enhancement of CDMA system capacity;and on the other it is also the requirement to maintain the stability of system." @default.
