Abstract
In order to solve the interference problem in a complex electromagnetic environment, NC-OFDM and TDCS are efficient transmit waveform. The spectral efficiency and the applicable environment of TDCS are different from NC-OFDM. The simulation results show that NC-OFDM can obtain the higher spectral efficiency and the required SINR is higher, and TDCS can work well in lower SINR environment with different spreading factor. When there is little spectrum hole, spread spectrum is a better choice. There is no threshold of some parameter which can make a decision. An artificial intelligence algorithm is proposed to select the optimal one from several waveforms. The input parameters of the algorithm include SINR, interference bandwidth, spectrum holes, etc.
