Abstract: A packet detection method of a receiver estimates noise power based on received samples and an orthogonal sequence that is orthogonal to a preamble sequence of a transmitter. The method verifies whether a packet is present in a radio channel based on the noise power. Also provided is a transmitter that selects a preamble sequence, modulates a transmission packet, and transmits the modulated transmission packet for reception by such a receiver.

Abstract: A near field communication (NFC) transceiver includes a receiver, a transmitter, and a clock recovery circuit. The receiver is configured to recover a reception (RX) frame encoded with power supply information and information transmitted from a reader to a tag. The transmitter is configured to recover a transmission (TX) frame by a subcarrier load modulation scheme for information transmitted from the tag to the reader. The clock recovery circuit is configured to recover a carrier signal of the TX frame as a baseband clock signal of the NFC transceiver through a rail-to-rail boosting.
