ICI mitigation of lte downlink system using modified local splines

Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) is an advanced technology of Universal Mobile Telecommunication System (UMTS) which has been developed keeping in view the increasing demand for high speeds in networks from users to access high quality multimedia content. Importance has to be given to downlink since aspects related to capacity and coverage are dependent on it. Features of 3GPP LTE include high data rates for downlink as well as uplink. Added features include low delay, latency and low bit error rates.;LTE downlink employs OFDM technology that primarily encounters a characteristic problem of Inter Carrier Interference (ICI). ICI in mobile environment is mainly due to time varying Doppler channel. This thesis primarily focuses on using modified local splines for mitigating the ICI. The system is evaluated in a high-delay and high-Doppler environment. The simulations show evidence that the use of modified local splines enhance the performance when compared to older techniques like piece-wise linear modeling in terms of probability of error.
