Abstract:
Method, apparatus and systems for object tracking are disclosed. In one example, a disclosed method includes obtaining at least one time series of channel information (CI) of a wireless multipath channel using: a processor, a memory communicatively coupled with the processor and a set of instructions stored in the memory. The at least one time series of channel information is extracted from a wireless signal transmitted between a Type 1 heterogeneous wireless device at a first position in a venue and a Type 2 heterogeneous wireless device at a second position in the venue through the wireless multipath channel. The wireless multipath channel is impacted by a current movement of an object in the venue. The method also includes determining a spatial-temporal information of the object based on at least one of: the at least one time series of channel information, a time parameter associated with the current movement, and a past spatial-temporal information of the object. The at least one time series of channel information is preprocessed. Associated computation may be shared among the processor, the Type 1 heterogeneous wireless device and the Type 2 heterogeneous wireless device.

Claim (Index 7):
The method of  claim 1 , further comprising:\n determining an initial spatial-temporal information of the object at an initial time prior to the current movement of the object based on another time series of another channel information (CI) associated with a prior movement of the object,\n wherein the another time series of the another channel information is extracted from a second wireless signal transmitted between a second Type 1 heterogeneous device at a third position in the venue and a second Type 2 heterogeneous device at a fourth position in the venue through the wireless multipath channel, \n wherein the wireless multipath channel is impacted by the prior movement of the object; \n determining the initial spatial-temporal information of the object at the initial time to be a known location associated with at least one of: the second Type 1 heterogeneous device and the second Type 2 heterogeneous device; determining a time period in which essentially all corresponding CI of the another time series of the another CI is at least one of: larger than a first adaptive threshold and smaller than a second adaptive threshold; and determining the initial time as a characteristic point of the time period, wherein the spatial-temporal information of the object is determined based on the initial spatial-temporal information of the object at the initial time,\n wherein the characteristic point of the time period is at least one of: a mid-point, a quartile point, a percentile point, a starting point, an ending point, a point at which the another CI is locally maximum, a point at which the another CI is locally minimum, a point at which the another CI has a certain characteristics, and another characteristic point.
