摘要: In this letter, we propose a method for blind separation of d co-channel BPSK signals arriving at an antenna array. Our involves two steps. the first step, received data vectors output array is grouped into 2/sup d/ clusters. second assign d-tuples with /spl plusmn/1 elements to these clusters in consistent fashion. From knowledge cluster which vector belongs, estimate bits transmitted that instant. Computer simulations are used study performance our method. >
