Abstract

In this paper, three approaches for channel estimation method are proposed and analyzed for third generation (3G) Wideband Code Division Multiple Access (W-CDMA) communication systems. The down link (DL) channel estimation schemes researched are to use time multiplexed pilot - data symbols, code multiplexed common pilot channel (CPICH), and to combine the channel estimate results from these two approaches which is called combined channel estimation (CCE). For channel estimates using time multiplexed pilot-data symbols, we propose a new algorithm called Iterative Multi-slot Averaged Linear Interpolation (IMALI). These methods are modeled and analyzed by means of computer simulations under multipath Raleigh fading channel and compared to the ideal channel estimation result. IMALI and CCE schemes show improvement in channel estimation accuracy and BER performance for high Doppler Frequency.
