Abstract

A system and method of encoding a binary datastream for wireless transmission combining characteristics of OFDM and FBMC type systems is proposed, based on a precoding schemes adapted to maintaining real orthogonality so that the output of the OTFS processing consists of real-valued symbols. The precoder is intricately linked to the definition of a subsequent 2d linear phase rotation. Two possible precoder architectures are proposed, in which interleaver and conjugate operations process partwise or en bloc the incoming data matrix, before the original matrix is concatenated with the interleaved and conjugated matrix (or its components) to obtain a new matrix for subcarrier allocation and filter bank encoding prior to transmission. Corresponding receiving mechanisms are proposed.
