Processing Procedure of WCDMA System

  • Source coding can increase the transmitting efficiency.
  • Channel coding can make the transmission more reliable.
  • Spreading can increase the capability of overcoming interference.
  • Through the modulation, the signals will transfer to radio signals from digital signals.

Bit, Symbol, Chip

  • Bit : data after source coding
  • Symbol: data after channel coding and interleaving
  • Chip: data after spreading
