Abstract:
Fiber, cable, and wireless data channels are typically impaired by reflectors and other imperfections, producing a channel state with echoes and frequency shifts in data waveforms. Here, methods of using OTFS pilot symbol waveform bursts to automatically produce a detailed 2D model of the channel state are presented. This 2D channel state can then be used to optimize data transmission. For wireless data channels, an even more detailed 2D model of channel state can be produced by using polarization and multiple antennas in the process. Once 2D channel states are known, the system turns imperfect data channels from a liability to an advantage by using channel imperfections to boost data transmission rates. The methods can be used to improve legacy data transmission modes in multiple types of media, and are particularly useful for producing new types of robust and high capacity wireless communications using non-legacy OTFS data transmission methods.

Claim (Index 33):
The method of  claim 28 , wherein the plurality of OTFS pilot symbols P pt,pf  is known by the at least one receiver, wherein the plurality of OTFS pilot symbols is further chosen to be any of: one- or two-dimensional m-sequences comprising binary maximal-length shift register sequences, delta values P i,j  surrounded by regions of P pt,pf  zero values, one- or two-dimensional Barker codes, Costas arrays, Walsh matrixes, or other plurality of pilot symbols selected to facilitate acquiring said 2D channel state, and wherein the 2D pilot OTFS time-frequency bin structure comprises time-frequency resolutions that are equal to or more precise than time-frequency resolutions of the OTFS time-frequency grid.
