Abstract :
Baseband PRS signals do not contain any spectral components at the symbol rate or submultiples thereof. For this reason difficulty is frequently experienced in synchronising a PRS receiver with the data transmitter. This article presents a description of a novel synchronization scheme developed for such signals-using digital signal processing (DSP) techniques. A channel filter with a response derived from the raised cosine (RC) frequency response is used. This is followed by a limited amount of processing, resulting in a substantial signal at the required frequency
