- 초록
- A novel waveform design approach is taken to develop a waveform based on precoding of data symbols, referred to as Precoded OFDM. The waveform is tailored for robustness against asynchronous transmission and a simple OFDM receiver to keep its intricacies hidden from the system. These features are most desired in massive Machine Type Communications (mMTC) where better intrinsic robustness is critical in avoiding the overheads used in cellular systems for synchronization.
