摘要： Provided is a channel estimation apparatus and method. In the channel estimation apparatus, a channel estimator performs channel estimation onto a received symbol and output a channel estimation result. The channel estimation result is stored in an estimation buffer along with a channel estimation result compensated in a preamble phase compensator. The preamble phase compensator receives a channel estimation result for pilot subcarriers of a data symbol and a preamble channel estimation result from the estimation buffer, acquires a phase rotation value between them, and compensates the preamble channel estimation result with the phase rotation value. When FCH and DL-MAP are demodulated, pilot subcarriers in the Nth PUSC symbol have been used to estimate the channel of the Nth PUSC symbol.

摘要： An apparatus and method are provided for estimating a Carrier-to-Interference-and-Noise Ratio (CINR) in a communication system based on Orthogonal Frequency Division Multiplexing (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA). In the communication system, all base stations boost a power level for a preamble or pilot by B dB. Accordingly, a received signal power level and a received interference level are boosted by B dB, but a noise level is not boosted. Transmission power for a preamble or pilot interval is boosted as compared with that for the data interval. After an interference and noise level is estimated from a preamble or pilot, the interference and noise level estimate of the preamble or pilot is corrected by taking into account a boosting level of the preamble or pilot.

摘要： In an apparatus for estimating a Carrier-to-Interference-and-Noise Ratio (CINR) in a communication system, received signals are blocked based on sub-carriers with similar channel characteristics. Interference and noise levels and true received signal levels are computed on a block-by-block basis from the blocked received signals. CINRs are estimated on a block-by-block basis using ratios between the computed interference and noise levels and the computed true received signal levels. The apparatus can estimate a CINR for all channels even when the channel characteristics of the sub-carriers of the received signals are not similar to each other.

摘要： An apparatus and a method for estimating a carrier to interference and noise ratio (CINR) in a communication system. The CINR value is precisely estimated by removing the error floor value, which is caused by the inaccurate sliding average window SAW channel estimation value, from the CINR estimation value. Since the CINR value is precisely estimated, performance of the adaptive power control or the adaptive modulation and coding device is improved.
