Generalized multicarrier DS-CDMA using various chip waveforms
Lie‐Liang Yang, Lajos Hanzo · 2004
In this contribution the family of generalized multicarrier DS-CDMA (MC DS-CDMA) schemes is investigated, when considering time-domain half-sine and raised-cosine chip waveforms, in addition to the rectangular chip waveform. Our results show that for a given subcarrier spacing the particular choice of the chip waveform has a substantial influence on the system's performance. However, in the context of MC DS-CDMA using the optimum subcarrier spacing, all chip waveforms may provide a similar bit error rate (BER) performance.
