Abstract :
This work introduces a new transform-based time interleaving algorithm: FTI-OFDM (Fourier transform interleaved OFDM) in which binary information is spread over several consecutive symbols that can be further scrambled in the frequency domain. Simulations are used to show its superiority over the usual binary time interleaving used in ordinary OFDM under several impairment scenarios that include impulsive noise and deep fading
