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
