Title:	Arbitrary waveform coded excitation using bipolar square wave pulsers
Authors:	Huang, SW;Li, PC
Contributors:	Division of Medical Engineering Research
Abstract:	This paper presents a new coded excitation scheme that efficiently synthesizes codes for arbitrary waveforms using a bipolar square wave pulser. The key idea of the proposed method is the conversion of a nonbinary code with good compression performance into a binary code by code translation and code tuning. Tukey-windowed chirps were converted into binary Tukey-windowed chirps that were compared with pseudochirps over the same spectral band. Experimental results show that the use of binary Tukey-windowed chirps can reduce the code duration by 20% or the peak sidelobe level by 6 dB compared to the commonly used pseudochirps.
