/** \brief This function performs channel compensation (matched filtering) on the received RBs for this allocation. In addition, it computes the squared-magnitude of the channel with weightings for 16QAM/64QAM detection as well as dual-stream detection (cross-correlation)
@param rxdataF_ext Frequency-domain received signal in RBs to be demodulated
@param ul_ch_estimates_ext Frequency-domain channel estimates in RBs to be demodulated
@param ul_ch_mag First Channel magnitudes (16QAM/64QAM)
@param ul_ch_magb Second weighted Channel magnitudes (64QAM)
@param ul_ch_mag First Channel magnitudes (16QAM/64QAM/256QAM)
@param ul_ch_magb Second weighted Channel magnitudes (64QAM/256QAM)
@param ul_ch_magc Third weighted Channel magnitudes (256QAM)
