Purpose of WCDMA Channelization Code Channelization code is used to distinguish different physical channels of one transmitter For downlink, channelization code ( OVSF code ) is used to separate different…

Spreading Technology in WCDMA

Spreading consists of 2 steps: Channelization operation, which transforms data symbols into chips Scrambling operation is applied to the spreading signal Spreading means increasing the bandwidth of the signal beyond…
