A METHOD OF REALIZING SMART ANTENNA BASED ON SOFTWARE RADIO AND SYSTEM THEREFOR

摘要

The present invention relates to a method implementing intelligent antenna based on software radio and intelligent antenna implemented system, is applied to the IMT-2000 CDMA system classifies the channel environment by the features of the wireless communication channel environment, and space flattened differential processing way through the process of converting the covariance matrix of the array receives the signal progressively in descending dimension (descending dimension) independent signal source for correlating the correlation signal gradually eliminates Due to obtain the correlation structure of the received signal by using the environmental identification implementation, by selecting the corresponding received adaptive beamforming calculation and transmission adaptive beamforming by calculation that the result of the classification channel environment and calculates the reception weight and the transmission weight, respectively. The invention when because using an adaptive beam forming method of smart antenna based on software radio compared to the existing adaptive beam forming method was to avoid localized adaptive beamforming method adaptable wide and a single, upgrade of the base station system and It can advantageously shift to the protection and effectively control the effects of interference. ; IMT-2000, CDMA, intelligent antenna, wireless soteuteuweeo
