- Abstract
- Provided are a pilot transmitting apparatus and method capable of selectively using an OFDMA scheme and an SC-FDMA scheme. The pilot transmitting apparatus includes a pilot inserter for inserting a pilot signal in a modulated symbol and inserting a cyclic prefix code for the inserted pilot signal, an FFT processor for receiving symbols with a pilot inserted thereto from the pilot inserter and performing an FFT process on the received symbols, an IFFT processor for receiving the transformed data from the FFT processor and performing an IFFT process on the transformed data, a mapping processor for mapping the output of the FFT processor to input positions of the IFFT processor to load the frequency domain transformed data on predetermined sub-carriers, and a cyclic prefix inserter for inserting a cyclic prefix code for the output of the IFFT processor.
