Abstract: In one aspect, a method includes performing a mapping on bits to form a complex data symbol, applying a frequency rotation mask to the complex data symbol based on a polynomial phase, performing an inverse discrete Fourier transform (IDFT) after applying the frequency rotation mask, applying a time domain window after performing the IDFT, converting digital data to analog data after applying the time window and transmitting the analog data as an analog signal.

Abstract translation: 在一个方面，一种方法包括：对比特进行映射以形成复数据符号，基于多项式相位对复数数据符号应用频率旋转掩码，在施加频率旋转掩码之后执行离散傅里叶逆变换（IDFT） ，在执行IDFT之后应用时域窗口，在应用时间窗口之后将数字数据转换为模拟数据，并将模拟数据作为模拟信号发送。
