Abstract

Carrier-to-interference ratio (CIR) plays a vital role in the uplink/downlink process of OFDM. Due to frequency offset (FO) there might be loss of orthogonality in OFDM modulated symbol there by signal-to-noise ratio will be reduced, it also introduce a timing jitter which can be defined as the deviation of timing edges from its expected areas. Jitter causes serious hardware impairments due to the synchronization imbalance. Hence, we have implemented a typical jitter noise reduction method which also improves the CIR performance there by degrades the intercarrier interference (ICI). We execute ultra-sampling criteria in the OFDM correspondence framework, by adjusting over examining in the framework we get lessened jitter power which enhances CIR performance which results in mitigation of ICI factor.
