Abstract: An adaptive wakeup methodology may be implemented to allow an radio frequency identification (RFID) tag to stay synchronized with periodic radio frequency (RF) interrogator polling signal while at the same time optimizing power consumption. A receiver (or transceiver) component of a RFID tag may only be operated when an interrogator polling signal is expected, and in a manner that reduces the amount of time between when the receiver or transceiver is turned on and when the interrogator polling signal is received (i.e., the receive buffer time). At other times, the RFID tag may be placed in a low power consumption sleep state. The amount of time that the RFID tag spends in such a low power sleep state before waking and receiving the following interrogator polling signal may also be optionally adjusted, e.g., to fit characteristics of a given situation and/or to re-synchronize a given aRFID tag with first band transmissions from an aRFIDI.

Abstract: This invention describes a programmable, digital implementation to shift an arbitrary frequency, or various frequencies in various communication systems of the original signal in the frequency domain. The correspondent phase accumulation to perform the desired frequency shift per sampling instant is perfectly tracked by counting up or down a simple integer. Several arbitrary frequency shifters with different mathematical models are provided. The correspondent implementations with Look-Up-Tables (LUT) are derived for high-speed implementations without further calculations of the values of the sine and cosine functions every sampling instant. Furthermore, a simple shift-and-add phase rotation is described to replace the four required real multiplications. If the original complex signal contains only one-bit each from real part and imaginary part, a surprisingly simple implementation is derived and disclosed for the overall arbitrary frequency shift operation.
