Abstract
An improved antenna array (AA) has been introduced, in which reverse-link synchronous transmission technique (RLSTT) is incorporated to effectively make better an estimation of covariance matrices at a beamformer-RAKE receiver. While RLSTT is effective in the first finger at the RAKE receiver in order to reject multiple-access interference (MAI), the beamformer estimates the desired user's complex weights, enhancing its signal and reducing cochannel interference (CCI) from the other directions. In this work, it is attempted to provide a comprehensive analysis of user capacity which reflects several important factors such as the shape of multipath intensity profile (MIP), the number of antennas, and power control error (). Theoretical analysis, confirmed by the simulations, demonstrates that the orthogonality provided by employing RLSTT along with AA may make the DS-CDMA system insensitive to the even with fewer numbers of antennas.
