Apparatus and method for estimating channel in communication system supporting OFDM/OFDMA |
摘要 |
Disclosed are an apparatus and a method for estimating a channel in a base station when using a Partial Usage of Sub-Channels (PUSC) mode in an uplink channel of the communication system supporting Orthogonal Frequency Division Multiplexing/Orthogonal Frequency Division Multiple Access (OFDM/OFDMA). For this, the channel estimation apparatus used in the communication system supporting the OFDM/OFDMA comprises a phase estimation/compensation unit estimating and compensating phase change of a channel by using pilots included in signals input by sub-channel; and a channel estimation unit estimating the channel by averaging the pilots of the signals of which the phase is compensated. |
