Abstract: Methods and devices for generating a voltage waveform at an output may include providing four DC voltages of different magnitudes. The first (V1) magnitude is higher than the third (V3) and fourth (V4) magnitude. The fourth DC voltage is coupled to the output followed by coupling the first DC voltage to the output, to bring an output voltage (VP) at the output to a high level.

A ground potential (V0) is coupled to the output following coupling the third DC voltage and the second DC current (I2) is coupled to the output following coupling the ground potential, wherein the second DC current ramps down the output voltage (VP).

Abstract: 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.
