A receiver/transmitter device for logistics tracking configured to monitor or detect a shipment unit includes: a cellular transmitter for transmission of wireless signals via a cellular network; an ultra-wide band (UWB) transmitter for transmission of radio signals over a short-range network; a radio frequency identification (RFID) reader configured to detect a passive RFID tag associated with the shipment unit; and a processor in communication with the cellular transmitter, UWB transmitter, and RFID reader. The processor is configured to selectively cause the cellular transmitter or the UWB transmitter to wirelessly transmit information detected by the RFID reader to a remote computing device or computer server. The device also includes a housing configured to be mounted to a transport platform that encloses the cellular transmitter, UWB transmitter, RFID reader, and processor.

Passive reader and active receiver/transmitter devices for logistics tracking

This disclosure provides a system and method for separating a first signal from a second signal of a plurality of constituent signals within a composite signal. The method can include receiving a first portion of the composite signal at a first clock rate and exponentiating it to detect the first signal and the second signal within the composite signal and determine modulation estimates of the first and second signals and at least one symbol rate. The method can also include resampling the first portion based on the modulation estimates at x-times the at least one symbol rate to determine symbol trajectory, modulation type, and offset information between the first signal and the second signal. The method can include determining a synthesized first signal and a synthesized second signal representing the first signal and the second signal within the first period of time at a second clock rate that is a multiple of the first clock rate.
