| Abstract: | In this paper, a general expression for the output signal to interference and noise ratio,SINR(W), is derived. The signal to interference and noise approving ratio, SINRIR (W). is defined. By means of PIC, a postbeamformer interfernce canceller, a trace of the moving signal bearing is detected. By the theoretic analysis and computer simulations in de-tail, we proposed the adaptable condition and area of PIC, and solved the problem of actual applications of PIC. |
