The present invention relates to an interference cancellation receiving method in an OFDMA mobile communication
system, and an apparatus using the same. For this purpose, the present invention provides an interference cancellation receiving method for outputting a data symbol from which an interfering
signal is canceled by receiving subcarriers including a
data signal from a serving
base station, the
data signal including interfering signals from a neighboring
base station and a
remote base station, estimating a channel response of the serving
base station and the neighboring base
station by using at least one adjacent
pilot subcarrier in the
frequency axis or time axis, computing a
weight value for canceling the interfering signals, and combining at least one data
subcarrier having a repeated identical data symbol among received subcarriers with the
weight value. According to the present invention, performance of receiving serving base
station signals is improved, and a success rate of handoff is increased and handoff
delay time is reduced by successful decoding of signals from a serving base
station and a neighboring base station when handoff occurs.
