    摘要: Disclosed is a device and method for compensating for phase distortions in a base station of an OFDMA-based cellular system. The method comprises receiving OFDM symbols from a plurality of mobile stations, canceling a symbol guard interval using a reference timing signal, and performing an FFT (fast Fourier transform) process on the OFDM symbols; dividing the OFDM symbols that have undergone FFT processing into subchannel groups of the mobile stations; restoring phases of the OFDM symbols divided into subchannel groups; and performing channel estimation and equalization on the restored OFDM symbols for each mobile station to thereby perform a demodulation process.

    摘要: A photoresist composition for immersion lithography and a method of forming a photoresist pattern using the photoresist composition are disclosed. The photoresist composition includes a photosensitive polymer including a cycloaliphatic group blocked with at least two cyclic acetal groups as a side chain, a photoacid generator and an organic solvent. The hydrophobic photoresist composition may be changed into the hydrophilic photoresist composition by an exposure process. Thus, before the exposure process, the photoresist composition may be insoluble in a liquid for the immersion lithography. After the exposure process, an exposure portion of a photoresist film formed using the photoresist composition may be effectively dissolved in a developing solution to form a uniform photoresist pattern.
