Generated by the MATLAB program 2Gbi/s baseband OFDM signal the first 2 ^ 15-1 pseudo-random sequence is mapped to 256 for 4QAM code modulation subcarriers, OFDM symbol after the re-encoded after IFFT transformation to convert it too domain waveform, and then add 6.4ns the cyclic prefix (CP), the data generated by Tektronix waveform and then loaded into the arbitrary waveform generator (AWG), resulting in 2Gbit/s baseband OFDM signal. Schematic diagram of the baseband OFDM signal spectrum shown in Figure 3. Including 256 sub-carrier OFDM subcarriers 256, 200 subchannels used to transmit data signals, 27 high and 28 low-frequency sub-channel over-sampling of the need to set 0, OFDM spectrum in the most middle of the baseband sub-channel as large DC component signal is also set to 0.
