摘要： Methods and systems for optimal frequency planning for an integrated communication system with multiple receivers may include adjusting a center frequency of a low IF signal to reduce interference by a second order interference signal. The center frequency may be adjusted to avoid high power portions of the second order interference signal. The interference level corresponding to a center frequency may be determined by, for example, a SNR of the low IF signal, or by determining a BER for the low IF signal. The center frequency of the low IF signal may be dynamically adjusted to keep second order interference level at an acceptable level. Adjusting the center frequency of the low IF signal may also comprise keeping the low IF signal from being blocked by a DC component of the second order interference signal.

摘要： An RFID system includes an RFID tag, an RFID reader, and a server. The RFID tag communicates to the server via encrypted information. The information may be encrypted with synchronized encryption keys. In this manner, the reader need not decrypt the information from the RFID tag. The effectiveness of malicious readers is thereby reduced, resulting in improved RFID tag security.

摘要： A highly integrated and low-cost reader for a radio frequency identification (RFID) system is realized by providing a transmitter operable to generate an outbound radio frequency (RF) signal and a receiver operable to receive an inbound RF signal having a frequency similar to a frequency of the outbound RF signal on a single integrated circuit. Since the inbound RF signal may include not only a modulated RF signal produced by an RFID tag responsive to the outbound RF signal, but also a blocking signal corresponding to the outbound RF signal, the receiver additionally includes a block cancellation module operable to substantially cancel the blocking signal from the inbound RF signal using the outbound RF signal and to substantially pass the modulated RF signal before down-conversion of the modulated RF signal.
