It has been proposed recently to replace the cyclic prefix (CP) in OFDM transmission by zero-padding (ZP); this guarantees symbol recovery even when channel s are located on a subcarrier. This, though, has the disadvantage that the simple DFT-based receiver does not perform well, but ...
When the channel delay spread is larger than the guard interval of zero-padded (ZP) OFDM transmissions, interblock interference (IBI) might lead to significant performance degradation. Without altering the signal design, a time-domain equalizer (TEQ) can be applied at the receiver to shorten the...

We derive a block linear MMSE equalizer suitable for zero padded multicarrier systems with insufficient guard length. The proposed equalizer is not limited to systems using the IFFT/FFT pair (like in DMT or OFDM), but to any multicarrier system that can be modelled as a pair of perfect reco...

A GI consisting of all zeros is also known, and the technique is referred to as Zero Padding (ZP–OFDM). ZP–OFDM performs very well, but suffers from a complexity problem. This paper provides two improved and low-complexity receiver designs for ZP–OFDM, which make the convolutions ...
