OFDM Timing Jitter Reduction by Oversampling

OFDM offers many advantages in terms of resilience to fading, reflections and the like. OFDM also offers a high level of spectrum efficiency. However to reap the rewards, it is necessary that the OFDM system operates correctly, and to achieve this, it is necessary for the OFDM synchronization to be effective. There are a number of areas in which the OFDM synchronization is critical to the operation of the system, but this paper only deals with OFDM synchronization in terms of clock accuracy and proposes an oversampling based technique to ensure that the samples are synchronized and data errors are minimized.
