    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 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 data transmission methods as well.

    Abstract: Methods, systems and devices for wireless communication, which include localization and auto-calibration, are described. One example method includes receiving, at a wireless device, signal transmissions from one or more network devices, and generating, by processing the signal transmissions, a feedback signal for antenna calibration of the one or more network devices. In some embodiments, the antenna calibration is used for performing device localization and feature map generation that is subsequently used for scheduling transmissions in a wireless network.

    Abstract: Methods, apparatus and systems for wireless communication are described. One example method includes estimating, based on channel quality information for a first communication channel during a first time interval, a predicted quality of a second communication channel during a second time interval that is a latency interval after the first time interval and using the predicted quality for processing transmissions on the second communication channel during the second time interval.

    Abstract: Computerized wireless transmitter/receiver system that automatically uses combinations of various methods, including transmitting data symbols by weighing or modulating a family of time shifted and frequency shifted waveforms bursts, pilot symbol methods, error detection methods, MIMO methods, and other methods, to automatically determine the structure of a data channel, and automatically compensate for signal distortions caused by various structural aspects of the data channel, as well as changes in channel structure. Often the data channel is a two or three dimensional space in which various wireless transmitters, receivers and signal reflectors are moving. The invention's modulation methods detect locations and speeds of various reflectors and other channel impairments. Error detection schemes, variation of modulation methods, and MIMO techniques further detect and compensate for impairments. The invention can automatically optimize its operational parameters, and produce a deterministic non-fading signal in environments in which other methods would likely degrade.

    Abstract: Methods, systems and devices for wireless communication are described. One example method includes performing a first mapping in which information bits are mapped to transmission resources in a first portion of a two-dimensional delay-Doppler grid. Herein, the two-dimensional delay-Doppler grid comprises N Doppler elements and M delay elements, where N and M are positive integers. The method further includes performing a second mapping in which a reference signal is mapped to transmission resources in a second portion of the two-dimensional delay-Doppler grid, and generating a transmission waveform from a signal combination of an output of the first mapping and an output of the second mapping. The transmission waveform corresponds to an output of an orthogonal time frequency space (OTFS) waveform of the signal combination, and at least the output of the second mapping undergoes a time domain spreading.
