Questions about the technology: 1. How does the application of delay and Doppler shift improve signal transmission in wireless communication? 2. What are the potential challenges in implementing this technology in real-world wireless networks?
Original Abstract Submitted
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may apply at least one of an amount of delay or an amount of Doppler shift to a signal transmission including a first signal for transmission from a first antenna and a second signal for transmission from a second antenna, wherein the second signal is shifted, relative to the first signal, in a delay-Doppler domain, by the at least one of the amount of delay or the amount of Doppler shift. The transmitter may output, in a time-frequency domain, the first signal from the first antenna and the second signal from a second antenna. Numerous other aspects are described.
