REFERENCE SIGNAL DESIGN FOR ZERO-TAIL ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18046853 titled 'REFERENCE SIGNAL DESIGN FOR ZERO-TAIL ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATIONS
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications involving the generation and processing of time-domain and frequency-domain reference signal sequences.
- The transmitting device generates a time-domain reference signal sequence, truncates it to a specific length, appends header and tail portions, performs a DFT to obtain a frequency-domain reference signal sequence, and then an IFFT on the result before transmission.
- The receiving device processes the received signal by performing an FFT, dividing by a phase constant, and taking the conjugate of the sequence.
Potential Applications
This technology could be applied in various wireless communication systems, such as 5G networks, IoT devices, and satellite communications.
Problems Solved

Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A transmitting device may generate a first time-domain reference signal sequence of a first sequence length, and may truncate the first sequence length to a second sequence length and may append a header portion and a tail portion to the truncated first time-domain reference signal sequence. The transmitting device may perform a discrete Fourier transform (DFT) on the truncated first time-domain reference signal sequence to generate a frequency-domain reference signal sequence associated with a phase constant, and may perform an inverse fast-Fourier transform (IFFT) on the result of the DFT. The transmitting device may then transmit the result of the IFFT to a receiving device, which may further process the signal by performing a fast-Fourier transform (FFT), dividing by the phase constant, and taking the conjugate of the received sequence.
