Notes/Equations
  1. Relations between parameters for transport channel processing and transport channel format are not straightforward; this tool is provided to aid in the use of transport channel models.
    The basic function of this transport channel parameter calculator is to convert the transport format to other transport channel parameters defined in the 3GPP technical specification. These parameters include:
    • channel coding block size
    • channel coding block number
    • radio frame size
    • padded bits for channel coding
    • radio frame number
    • CRC encoder output size
    • channel coding input size
    • channel coding output size
    The schematic for this hierarchical example is shown in the following figure.
