Abstract :
We propose a new, low-complexity frequency-domain equalizer, which, in the absence of a guard interval, utilizes redundancy in the frequency domain to completely eliminate intersymbol and interchannel interference. Simulation results show that the new equalization scheme has at least the same potential compared to conventional DMT/OFDM while offering the shortest possible latency at a reasonable complexity enhancement.
