In a radio frequency identification (RFID) system that requires an RFID reader to receive a response from an RFID tag and then transmit a command to the RFID tag within a certain time period, the RFID reader may place an initial part of the command transmission in the RFID reader's transmit chain before receiving the entire response from the RFID tag, and complete the command transmission after receiving the entire response.

Mitigating processing latency in RFID exchanges

Mechanisms for reducing amplitude-modulated noise in a wireless transceiver are generally described. In one example, an apparatus includes a radio-frequency identification (RFID) transceiver, a digital-analog converter (DAC) coupled with the transceiver, a reconstruction filter coupled with the digital-analog converter, and hold logic associated with the reconstruction filter to enable the reconstruction filter to hold its output voltage.

Reducing amplitude modulated noise for a wireless transceiver

A method of detecting signals propagated on a carrier medium includes the step of determining a noise threshold level, relative to a noise floor on a carrier medium, such as for example POTS wiring. A peak threshold level is then determined relative to peaks of a data signal. A data threshold level is then calculated utilizing the noise threshold level and the peak threshold level. For example, the noise threshold level and the peak threshold level may be averaged to calculate the data threshold level. A data signal pulse is then detected on traversal of the data threshold level by the data signal.
