Abstract :
We investigate the design of an optimal set of analog signals with prescribed magnitude spectrum and quadratic phase structure such that the maximum cross correlation between signals in the set is minimized. Such a set of signals can be used as signature waveforms in multiuser CDMA communications. It is also useful in a number of signal processing applications. In this paper, we first summarize some recently derived analytic results for the maximum cross-correlation between two signals. Then, we present some illustrative numerical design examples to show the effectiveness of the proposed approach
