Notes/Equations
  1. This model is used to delay input data several frames for radio frame de-segmentation because output data from the Rake receiver has one frame delay.
    Each firing, Mp × Np tokens of out and one token of outSize are produced when Mp × Np tokens of in and one token of inSize are consumed.
    Mp × Np tokens of input data is one frame data of 10 ms. Because output data from the Rake receiver has one frame delay, this model delays input data (T − 1) frames (Mp × Np × (T − 1) tokens) and input data size (T − 1) tokens. In variable rate transmission, all data in one frame is not useful, only inSize tokens are valid. WCDMA3G_RadioFrameDeSeg concatenates T frames to one TTI data block. The first data block in TTI is delayed data, not useful.
    Refer to the following tables for the values of T and Mp.
  2. DL_PhyCHType is valid only when LinkDir = Downlink; UL_DPDCHType is valid only when LinkDir = Uplink.
