Error reduction of ultrasound harmonic Golay encoding with pulse-width-modulation (PWM) and orthogonal decoding
碩士 === 國立臺灣科技大學 === 電機工程系 === 104 === Quadrature phase shift is required in the ultrasound transmit end for harmonic Golay encoding. Nonetheless, typical 3-level square transmit waveform fails to reproduce the 90° phase shift and thus the resultant harmonic code is not exactly encoded as the phased-...
