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 44):
The apparatus of  claim 43 , wherein the direct OTFS pilot bursts are received at the at least one receiver as polarized direct OTFS pilot bursts comprising polarized wireless OTFS pilot symbol waveform bursts according to at least one polarization direction,\n where the wireless reflector is a polarization altering wireless reflector that alters a polarization direction of its reflected wireless OTFS waveform bursts according to a first reflector polarization operator, thereby producing replica polarized OTFS pilot bursts that comprise polarization shifted time-delayed and reflector Doppler-shifted replicas of the polarized direct OTFS pilot bursts, and wherein the code further causes the processor to further implement:\n detecting a direction of polarization of the channel-convoluted polarized OTFS pilot bursts; and \n using the direction of polarization of the channel-convoluted polarized OTFS pilot bursts to further determine the 2D channel state of the impaired data channel.
