Abstract
In this paper, we analyzed the nonlinear performance on the DS/CDMA Communication System. At the $BER=10^{-4}$, uniform chip waveforms have similar performance in the linear channel. However, non-uniform chip waveforms have about more 0.5[dB] power gain than the conventional raised-cosine chip waveforms. In the nonlinear HPA, non-uniform chip waveforms have worse BER performance than the uniform chip waveforms because of the high PAPR. In other words, non-uniform chip waveforms show similar performance as uniform chip waveforms if IBO (input back on) of 15[dB] is given.
