摘要

实值自正交有限长序列具有零旁瓣自相关函数，但要求发射放大器具有线性度。为了传输实值自正交有限长序列，提出了二值和三值被积码。这些代码通过传输路径集成，并导致具有类似于单周期正弦脉冲的芯片波形的代码。三值积分码的相关输出比二值积分码的相关输出具有更低的旁瓣误差。

Two-valued and three-valued integrand codes for real-valued self-orthogonal finite-length sequence

A real-valued self-orthogonal finite-length sequence has a zero sidelobe autocorrelation function, but requires linearity of the transmitter amplifier. The paper proposes two-valued and three-valued integrand codes in order to transmit the real-valued self-orthogonal finite-length sequence. The codes are integrated through a transmission path and lead to those with a chip waveform similar to a one-cycle sine pulse. The correlation output for the three-valued integrand code takes a lower sidelobe error than that for the two-valued integrand code.
