Title:
METHOD FOR ESTIMATING TRANSMISSION PATH CHARACTERISTIC OF RECEPTION SIGNAL AND CDMA RECEIVER
Document Type and Number:
Japanese Patent JP2003115783
Kind Code:
A
Abstract:
To improve the precision of reception processing using a pilot symbol without increasing the rate of the number of pilot symbols, or increasing the transmission power of the pilot symbol, or using any temporary judgement data.
A TFCI included in a control channel is decoded (including error correction) by a decoding part 108, and re-encoded by a re-encoding data generating part 112, and the re-encoded data are used as already known bits in the same way as pilot symbols, and the transmission path characteristics of the next frame are estimated by transmission path characteristic estimating parts 103-1-103-N, and synchronism detection is operated.
