Patent number: 11863256Abstract: The present invention discloses a channel equalization-free single-carrier broadband transmission method, including the following steps: obtaining a number of temporal-resolvable multi-paths, and delays and channel gain vectors corresponding to the multi-paths based on a channel impulse response; deliberately introducing, by a transmitter, a corresponding delay for a symbol sequence, so as to perform delay compensation, so that all multi-path signal components arrive at a receiver simultaneously and constructively after propagating over a time-dispersive channel, thereby avoiding inter-symbol interference in broadband transmission; and utilizing, by the transmitter, multiple antennas to perform path-based beamforming design. A time-dispersive channel can be transformed into a frequency-flat channel by means of the path-based ZF beamforming and delay alignment modulation. The present invention further proposes a channel equalization-free single-carrier broadband transmission system.Type: GrantFiled: April 13, 2022Date of Patent: January 2, 2024Assignee: SOUTHEAST UNIVERSITYInventors: Yong Zeng, Haiquan Lu
