Abstract

A smart antenna system using virtual array elements is proposed to increase the channel capacity of mobile communication systems. The proposed smart antenna system increases the degree of freedom using virtual array elements generated by complex conjugations of real array elements signals and sign compensations using the orthogonality between the user identification codes in the I and Q channels. The performance of the proposed system is analyzed under cdma2000 specifications in urban cell environments
