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 between adjacent carriers, but in principle between all carriers. This is known as Inter-Carrier Interference (ICI) and sometimes also referred to … Read more

Some Special Antenna Technologies and Scheduling Mode for LTE

Special Antenna Technologies MIMO and Beam Forming are critical features in determining the actual link budget required for the Operator’s network. However, these two features are also critical features from a capacity perspective as they can also improve the efficiency of frequency reuse and reduce the intra-frequency interference within the same cell as well as … Read more
