摘要

CDMA (gababordivision码分多址)通信是近年来提出的一种能够提供几乎平坦功率谱的通信方式。利用CMOS技术实现的超宽带高斯脉冲发生器作为产生芯片波形的基本元件，将gsm - cdma系统应用于超宽带通信。采用马尔可夫性时频二维扩频码。解释了马尔可夫SS码如何使传输信号的频谱变平。

Markovian SS codes flatten the spectrum of UWB Gaussian pulse

Gabor-division (GD) code division multiple access (CDMA) communication, which can provide almost flat power spectrum, has been recently proposed. Using a UWB Gaussian pulse generator implemented by CMOS technology as a fundamental component generating a chip waveform, we apply the GD-CDMA system for UWB communications. Time-frequency two dimensional spread spectrum (SS) codes with Markovity are employed. How Markovian SS codes flatten the spectrum of the transmitted signal is explained.
