Channel Bitstream
Depending on the spreading factor (symbol rate) of the channel, a minimum of 12 and a maximum of
384 symbols can be contained in a power control group. Depending on the modulation type, a symbol
consists of the following bits:
• BPSK: 1 bit (only the I–component is assigned)
• QPSK: 2 bits (I–component followed by the Q–component)
• 8PSK: 3 bits
• 16QAM: 4 bits
For each bit, a value is output (range 0,1).
