This is the bit rate after channel coding and before symbol coding. Channel coding is done in the FRC (FrameController) so the modulator will get the already-coded bit stream. Most of the channel coding mechanisms will addadditional bits to the data stream. Therefore if the net (un-coded) DR (data rate) is to be kept at a given level thebitrate must be increased in this entry scaled by the bit increase level at channel coding. For example if block codingis configured whereby every block of 4 bits gets 3 parity bits appended to it, the Bitrate entry must be calculatedas DR_net* 7/4.
