Title: Method of estimating doppler shifting and transmitting data thereof
Inventor: KIM GI JUN
IPC: H04B7/01
Filed: 2001-12-29
Abstract: PURPOSE: A doppler transition estimating method and a data transmission method using the same are provided to detect an accurate doppler transition value by measuring a doppler transition degree by using a receiving pilot signal. CONSTITUTION: When a tilt of a certain section is checked for each doppler transition degree, a certain tilt value on average exists according to the doppler transition degree. In general, the greater the doppler transition, the steeper the tilt. Based on this, a doppler transition value can be reversely estimated by obtaining a tilt degree of power received for every certain intervals. Each receiving power of pilot channels received by a slot unit is measured. Assuming that power of a signal received on ith slot is Pi and power of a signal received on I-1th slot is Pi-1, a tilt Ki of reception power change of pilot channels being received is obtained. An average value Si of the tilt K1 for N slots is calculated. The average value Si is compared with a tilt average value table corresponding to a doppler transmission previously obtained through a field test or simulation, in order to obtain an actually measured doppler transition value.
