Abstract
An OFDM receiver system for performing precise OFDM demodulation is provided. The OFDM receiver system performs demodulation by sharing memories and operators in a time-divisional manner. FFT-processed data is separated into specific pilot signals and data according to the timing indicated by a controller to then be rearranged and stored, thereby facilitating extraction of corresponding pilot signals and data for various synchronization and equalization steps. Therefore, the demodulation system having an optimal structure can be realized in view of resource utilization efficiency and chip areas, the cost and time for fabricating and designing the system can be reduced, and verification of the system can be easily performed.
