초록

This paper studies the channel estimation schemes of Time Division Duplex (TDD) Code Division Multiple Access (CDMA) system with a parallel interference cancellation (PIC) scheme in the multi-Path fading channel. Also, the effective interpolation scheme which maintains the merits of WCDMA TDD mode is proposed. By Monte Carlo simulations, it is shown that the proposed interpolation method can be used in order to obtain the proper performance of a multi-stage PIC and in order to reduce the required Eb/No in the second stage at a BER= 10$^{-2}$
