Normalize Chan. Freq. Resp. (LTE-Advanced)
Selected
determines how the frequency responses shown on the Eq Chan Freq Resp and MIMO Eq Chan Freq Resp traces are normalized.
When is selected, the channel frequency response of each C-RS Cell-specific RS/Rx path is normalized so that each path has an average per-subcarrier gain of 0 dB. Information about the gains of individual paths relative to each other is lost. In addition, any phase, frequency, or timing offset in the channel frequency response is removed.
When is cleared, only the reference C-RS/Rx path’s channel frequency response (shown in both the MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. and non-MIMO version of the trace) is normalized to have a per-subcarrier gain of 0 dB. In the trace, information about the gains of paths relative to each other is retained. In addition, any phase, frequency, or timing offset in each channel frequency response is not removed. This is helpful when calculating the condition number of the channel using the channel frequency responses of the individual paths.
The reference C-RS/Rx path is determined by the Ref Meas Channel and Ref C-RS Port parameters.
