Embodiment Construction

[0036] As previously discussed, the present invention is based in part on the inclination to look at signal strength variations (e.g., occasional signal fades, how long the signal remains coherent, the extent to which the signal frequency range can be expected to be coherent) due to the fact that some situations can only be handled by statistical methods. superior results can be obtained if the underlying structure of the communication channel is exposed, and virtually single out or "solve" the various causes of signal distortion (e.g., various reflections, frequency shifts, other shifts and the like).

[0037] Since a communication channel is used to transmit data, a communication channel will generally be referred to as a "data channel" throughout this disclosure. The main focus of this invention will be to transmit data through three spatial dimensions (often on Earth, where "space" can be filled with air and even other natural aerial objects such as clouds, raindrops, hail...

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 where other methods would likely degrade.
