Abstract
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.
