METHOD OF EQUALIZING DATA SYMBOL TRANSMITTED BY MOBILE TERMINAL TO BASE STATION IN MULTI-CARRIER CODE DIVISION MULTIPLE ACCESS TRANSMISSION NETWORK, BASE STATION AND MOBILE TERMINAL USED THEREFOR, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a device and a method of dynamically assigning subgroups of spreading sequences of a set of spreading sequences to mobile terminals of a Multi-Carrier transmission network. SOLUTION: Each of subgroups comprises different spreading sequences than the spreading sequences comprised in other subgroups, each subgroup of spreading sequences comprises a first spreading sequence and at least one other spreading sequence, each element of the first spreading sequence being, by the mobile terminal of which the first spreading sequence has been assigned, multiplied by pilot symbols to be transmitted and then transmitted on a corresponding sub-carrier, and each element of the at least one other spreading sequence being, by the mobile terminal of which the spreading sequence has been assigned, multiplied by data symbols to be transmitted and then transmitted on a corresponding sub-carrier. The method comprises also the equalization device and the method associated. COPYRIGHT: (C)2006,JPO&NCIPI
