Notes/Equations
  1. This subnetwork model is the uplink RF receiver for 3GPP FDD. This subnetwork consists of hierarchical models. The timed demodulator is at the front of this subnetwork; the demodulated I/Q signal is sent to the baseband receiver.
    The schematic for this subnetwork is shown in the following figure.

  2. Refer to 3GPPFDD_UL_Rx_RefCH and 3GPPFDD_UL_Rake for more information.
