Apparatus and method for receiving signals in multi-carrier multiple access systems

Abstract

A method for receiving signals in a multi-carrier multiple access system is disclosed. The method comprises receiving signals from at least one base station wherein each signal has a base station identifier, processing the signals to identify each base station by using the base station identifier, performing a channel estimation using the processed signals, combining the processed signals using an information obtained from the channel estimation and decoding the combined signals. Also, an apparatus for receiving signals in a multi-carrier multiple access system comprises a serial-to-parallel converter for converting a serial signal including a base station identifier from at least one base station to parallel signals, a Fast Fourier transformer for transforming the parallel signals, a parallel-to-serial converter for converting the parallel signals to a serial signal, a despreading processor for despreading frequency domain signals using the base station identifier from at least one base station, a channel estimator for compensating a channel variation between the at least one base station and a mobile station, a signal combiner for combining signals from base stations and a decoder for decoding the combined signal.
