/*!
\brief This function performs detection of the PRACH (=SRS) at the eNb to estimate the timing advance
The algorithm uses a time domain correlation with a downsampled version of the received signal.
\param rxdata Received time domain data for all rx antennas
\param frame_parms LTE DL frame parameter structure
\param length Length for correlation
\param peak_val pointer to value of returned peak
\param sync_corr_eNb pointer to correlation buffer
\return sync_pos Position of the sync within the frame (downsampled) if successfull and -1 if there was an error or no peak was detected.
