摘要：
A new orthogonal multicarrier bandwidth modulation (OMBM) scheme is proposed in this paper. The distinct feature of this scheme is that the frequency domain data is used to decide the number of orthogonal subcarriers for wireless transmissions. Different bandwidth of the OMBM symbol in the time domain reflects on the different data in the frequency domain. A Discrete Fourier Transform (DFT) based Minimum Mean Square Error (MMSE) estimator is employed to conduct the bandwidth detection. Analysis and simulation results demonstrate that the OMBM scheme is a flexible modulation structure and not sensitive to noise interference. Some properties and possible application of the OMBM code are also introduced.
