OFDM implementation in Detail
A typical OFDM transmitter is shown on the following figure. To reduce the amount of RF hardware required for OFDM the modulation process is split into two parts. A first part uses the inverse

Purpose of Channelization Code & Scrambling Code in WCDMA
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 physical channels of one
Inter-Carrier Interference for OFDM
The price for the optimum subcarrier spacing is the sensitivity of OFDM to frequency errors. If the receiver’s frequency is some fractions of the subcarrier spacing (subcarrier bandwidth) then we encounter not only interference
