摘要： A novel and useful electronic gyroscope exploits the Sagnac resulting in a detectable phase or frequency shift when an electromagnetic wave travels inside a rotating medium. These shifts in phase or frequency are measured and used to determine the angular velocity of the rotating medium. Three such media can be positioned in mutually perpendicular planes to detect 3D rotational movement. At least one loop acts as an RF transmission media that accommodates simultaneous bidirectional propagation of RF signals while being capable of separating between signals counter propagating in two opposite directions through the use of a switching matrix. A switching matrix and loop buffer function to sample pulses, amplify them, and reinject them back into one of the loops. A time measurement unit functions to detect the time difference between the counter propagating pulses which is used to calculate the rotation rate of the loop.

摘要： A novel and useful apparatus for and method of packet detection and carrier frequency offset estimation. The packet detection mechanism is robust to channels and sustains reasonable miss-detect (and false alarm) rates at low SNR values. The mechanism uses a modified combined cross correlation and delay and correlate scheme. A delay and correlate scheme is used in order to handle the effects of multipath while swapping integration and multiplication to increase cross-correlation factors resulting in improved sensitivity in low SNR conditions. Correlation is divided into multiple chains to generate a plurality of partial correlations to observe short patterns in the spread sequence resulting in improved performance in long multipath channels.

摘要： A radio frequency based electronic gyroscope function that may be incorporated in its entirety on a monolithic integrated circuit (IC). The detection and measurement of movement in a particular plane is based on the Sagnac effect as it applies to a radio frequency signal that propagates in two different directions in a loop that may be subject to rotational perturbation. In one embodiment, three mutually perpendicular loops that are incorporated into the same integrated circuit and are used to detect and measure movement in three planes (roll, pitch and yaw) thereby allowing a signal processing unit to quantify a general three dimensional movement. The gyroscope can be incorporated into an IC that is used in portable device, such as a mobile handset, to provide it with inertial navigation and movement detection and measurement capabilities.

摘要： Apparatus for amplifying an input signal having an input signal power includes a power amplifier, which is adapted to amplify an intermediate signal so as to generate an output signal, and which is characterized by a non-linearity. A non-linear filter is coupled to decompose the input signal into a series of input signal components, each such component proportional to a product of the input signal by a respective integer power of the input signal power, and is adapted to filter the signal components responsively to the non-linearity so as to generate the intermediate signal for input to the power amplifier.
