| Abstract(in English) | Coherent rake reception of direct sequence code division multiple access (DS-CDMA) signals requires accurate channel estimation in a frequency-selective fading channel. In this paper, we study the channel estimation method using FFT/IFFT for coherent DS-CDMA mobile radio using the code-multiplexed pilot structure. This channel estimation method can provide a good tracking capability against a fast fading channel and can effectively reduce the noise effect in the frequency-domain processing. The average bit error rate (BER) performance in a frequency-selective fading channel is evaluated by computer simulation. It is confirmed that this channel estimation method provides better BER performance than the conventional channel estimation method. |
