摘要： A channel estimation apparatus and method for an OFDM/OFDAM receiver. A channel characteristic value, positioned prior to a pilot symbol of a current slot, from among data symbols of the current slot is estimated by a time-domain interpolation method for use with a channel characteristic value of a pilot symbol of a previous slot and a channel characteristic value of the pilot symbol of the current slot. A channel characteristic value next to the pilot symbol of the current slot from among the data symbols of the current slot is estimated by a time-domain extrapolation method for use with the channel characteristic value of the pilot symbol of the previous slot and the channel characteristic value of the pilot symbol of the current slot.

摘要： Disclosed is a method and apparatus for efficiently controlling buffers which support a Hybrid Automatic Repeat Request (HARQ) in a wireless communication system. Buffer regions for the HARQ scheme are not fixedly allocated according to channel identification information, but are allocated from the viewpoint of one overall memory through aggregation support. That is, an HARQ buffer is dynamically controlled. Therefore, there are the effects reducing the size of the entire chip, as well as reducing power consumption of the entire system according to the reduction of the chip size.

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： A method and apparatus for processing time windowing to transmit a signal in a Broadband Wireless Access (BWA) communication system based on Orthogonal Frequency Division Multiple Access (OFDMA). A signal of a first interval included in a previous symbol prior to a current symbol is stored as a signal of a previous symbol interval. The current symbol includes a guard interval and an effective symbol interval subsequent to the guard interval. The current symbol is windowed by overlapping the stored signal of the first interval with a signal of a second interval included in the current symbol subsequent to the previous symbol. A windowed signal is transmitted.

摘要： Disclosed is an apparatus and a method for performing a cell search in a wireless communication system. A subscriber station calculates the power of subcarriers according to their positions in a preamble signal of a frequency domain and identifies a segment of a cell to which the subscriber station belongs. Then, the subscriber station correlates PN sequences, which correspond to the segment of the cell that has been identified, with the preamble signal of the frequency domain. Therefore, the number of calculations for determining correlation values in a cell search is remarkably reduced.

摘要： A method and HARQ memory apparatus in a BWA communication system are provided where the HARQ memory apparatus includes a memory configured to partition the entire memory area in units of slots corresponding to the size of a concatenation block, to input/output a plurality of channel data to the slot in units of the concatenation block, to store a new concatenation block in an empty slot, and to combine a retransmitted concatenation block with a prestored concatenation block and store the combined concatenation block at a prestored location. Accordingly, the required amount of memory can be reduced by using a buffer efficiently. In particular, when a memory is embedded in an integrated circuit, the size and power consumption of the integrated circuit can be reduced.
