A multicarrier direct-sequence code-division multiple access (MC-DS-CDMA) system
which employs an antenna array at the base-station
is introduced.A space-frequency blind adaptive algorithm (SFBA) based on maximum-signal-noise ratio (MSNR) principle is presented and the analysis of the performance of this algorithm is given.Neither the knowledge of the channel condition nor any training sequence is required.Using the characteristic of the CDMA signal
this algorithm can cancel the interferences and noise
and increase the SNR.The results of simulation show the feasibility
validity and resistance to near-far problem of this algorithm in Rayleigh fading channel.
