MOBILE STATION, BASE STATION, COMMUNICATION SYSTEM AND METHOD

摘要

FIELD: information technology. ^ SUBSTANCE: system comprises several mobile stations and a base station. A mobile station converts a pilot channel composed of a CAZAC code to a signal having a plurality of frequency components lying at equal intervals from each other in a given frequency band and transmits a transmission signal including such a signal in accordance with a scheduling signal. The mobile station also performs conversion so that its transmitted signal and transmitted signals of other mobile stations using different frequency bands become orthogonal to each other on a frequency axis. The base station calculates correlation between a received signal and the pilot channel reference signal, assesses the channel and demodulates the received signal based on the channel assessment result. The base station generates the pilot channel reference signal by converting the pilot channel which includes the CAZAC code to a signal which includes several frequency components lying at equal intervals from each other in a given frequency band. ^ EFFECT: reduced multi-station access noise. ^ 18 cl, 8 dwg
