This paper studies the channel estimation schemes of Time Division Duplex (TDD) Code Division Multiple Access (CDMA) system with a parallel interference canceller (PIC) in multi-path fading channels. Furthermore, the effective interpolation method which maintains the flexibility of Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (UTRA) TDD mode is proposed. By Monte Carlo simulations, it is verified 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 for a given bit error rate (BER).
