摘要：<p>A transmitter transmits data to a receiver using OFDM symbols including plural sub-carrier symbols, some carrying data symbols and some carrying pilot symbols. A data formatter can form the data for transmission into sets of data symbols for each OFDM symbol, and an OFDM symbol builder can receive each set of data symbols from the data formatter and combine the data symbols with pilot symbols. A modulator can map the data symbols and the pilot symbols onto modulation symbols and modulate the plural sub-carriers to form the OFDM symbols. An inverse Fourier transform can convert the OFDM symbols from the frequency domain to the time domain, and a guard interval inserter can add a guard interval to each of the OFDM symbols by copying a part of the OFDM symbols and appending the copied part sequentially in the time domain to the OFDM symbols.</p>
