  • Multi-carrier code division multiple access(MC-CDMA) is a hybrid of orthogonal frequency division multiplexing(OFDM)and code division multiple access(CDMA).To resist co-interference of MC-CDMA system,smart antenna are used in MC-CDMA. A blind adaptive array algorithm was developed for MC-CDMA system by using recursive least-squares dispread respread multitarget array. The proposed algorithm without training sequence for adaptive beamforming doesn't waste extra-spectrum by utilizing information of CDMA spreading codes. Compared with the RLS-DRMTA,the extended RLS-DRMTA algorithm proposed is less computation-consuming. The high performance of the system is achieved by post-FFT beamforming. Subcarrier clustering is applied to reduce the complexity. But subcarrier clustering reduce the performance of the system .So the complexity and the performance of the system are considered in clustering subcarrier. The results of simulations can be shown by the RLS-DRMTA algorithm that the array focuses energy in the required direction,which helps to reduce the interference.
