Location-assisted channel estimation methods in wireless communications systems

A system comprising:

• at least one wireless transmitter configured to wirelessly transmit a plurality of symbols to at least one wireless receiver through a multi-dimensional data channel connecting the at least one wireless transmitter to the at least one wireless receiver,
• wherein the multi-dimensional data channel comprising at least two dimensions of space and one dimension of time,
• wherein the multi-dimensional data channel further comprises at least one wireless reflector, wherein each of the at least one wireless reflector comprises a reflector location, velocity, and at least one coefficient of wireless reflection,
• wherein each of the at least one wireless transmitter further comprises a wireless transmitter location and velocity, and at least one transmitter processor,
• wherein each of the at least one wireless receiver further comprises a wireless receiver location and velocity, and at least one receiver processor,
• wherein the at least one wireless transmitter is further configured to transmit, at least for the plurality of symbols that are data symbols, the data symbols as originally transmitted wireless waveform bursts, wherein a plurality of data symbols comprise the data symbols,
• wherein the at least one wireless receiver is configured to receive channel convoluted waveform bursts due to the originally transmitted wireless waveform bursts propagating through the multi-dimensional data channel,
• wherein the at least one wireless receiver configured to use the at least one receiver processor to process the channel convoluted waveform bursts to determine channel response parameters of the multi-dimensional data channel between the at least one wireless transmitter and the at least one wireless receiver,
• wherein the channel response parameters are initially determined based on the wireless transmitter location that is obtained from Global Positioning System (GPS) signals, and
• wherein the at least one receiver processor is further configured to use the channel response parameters to extract the plurality of data symbols from at least an approximation of the originally transmitted wireless waveform bursts, thereby receiving at least some of the data symbols transmitted between the at least one wireless transmitter and at least one wireless receiver.
