A Pre-FFT Equalizer (PFE) has been shown to offer a significant throughput efficiency improvement when applied to an OFDM receiver. In this paper, the required computational complexity to implement such an equalizer is evaluated assuming the LMS adaptation algorithm. The paper concludes by discussing the potential efficiency and complexity trade-offs that can be achieved when applying this technology to standards such as Hiperlan E, IEEE P802.Ila and DVB-T.
