Abstract: This application presents inverse signal transformation (IST) reversing transmission channel transfer function, in order to achieve a direct recovery of original data and synchronizing clock from received signals affected by all deterministic and random distortions introduced by the channel. The direct data recovery can eliminate an intermediate recovery of signal transmitted originally from received signal, required in conventional solutions before actual data recovery can be made. Therefore IST can prevent signal processing errors added by such intermediate recovery and reduce power consumption and computing resources required in conventional receivers.

Abstract: A method, system and apparatus for noise filtering inverse transformation (NFIT), recovering phases and amplitudes of singular cycles of data carrying tones or sub-bands from a composite signal such as OFDM, is presented herein.
