A CHANNEL ESTIMATING METHOD AND APPARATUS THEREOF

摘要

The present invention discloses a method and apparatus of time division pilot channel estimation using in the spread spectrum communication technology, which obtain the phase and amplitude estimation value of the channel using the adjacent pilot signals, and correct the amplitude of one of the pilot symbol utilizing the power control instruction know to the receiver corresponding to the pilot signal, and acquire channel estimation result among the traffic signal by interposing values. The present invention can be suitable to various modulating manner, especially multi-level modulating manner in the CDMA system with power control, so as to significantly improve the performance of the mobile communication system.
