The effect of chip waveform shaping on the synchronization performance of DS-CDMA signals

The impact of chip waveform shaping on the synchronization performance of DS-CDMA signals is investigated. Acquisition and tracking performance are compared for signals with both full-response and partial response pulses. To ensure fair comparison, all pulses are prefiltered to occupy the same bandwidth. It is shown that full-response pulses significantly outperform the partial-response waveforms from the acquisition performance prospective. However, for tracking performance, the partial-response pulses are marginally superior to the full-response ones.
