摘要： Characteristics of the radio channel are used to establish pseudorandom sequences for use in communicating information. These characteristics are the short-term reciprocity and rapid spatial decorrelation of phase of the radio channel. Due to the reciprocal nature of these radio channel characteristics, the transceivers which are communicating via the radio channel will generally both determine the same sequence. Although the determined sequences are not always sufficiently random for use in pseudorandom functions, a randomness tester can be provided to discard those sequences which are not sufficiently random. Exemplary pseudorandom communication functions include the selection of a spreading sequence in CDMA systems and the selection of a hopping sequence in a TDMA or CDMA system.

摘要： In a time division multiple access spacecraft communication system, each ground station determines when to send its information packets to arrive at the spacecraft at the beginning of a time slot. The calculation is based upon knowledge of the location of the spacecraft. A master ground station determines the location of the spacecraft by the use of the propagation delays between the various ground stations (including itself) and the spacecraft, together with knowledge of the locations of the ground stations. The spacecraft location is then transmitted back to the various ground stations. The determination of propagation delay by each ground station is performed in two major steps. The first step determines coarse time delay to within one bit interval by repeatedly transmitting a multibit unique word to the spacecraft, and counting bits until the next unique word is received from the spacecraft. To determine fine propagation delay, a high-frequency clock signal is counted from the time of transmission of each bit edge until the reception of the next bit edge. The sum of the coarse and fine delays, together with a plurality of frame intervals, establishes the range to the spacecraft.

摘要： A system for determining a maximum length digital sequence is constructed by selecting a Mersenne Prime integer and a primitive polynomial having an ORDER equal to the Mersenne Prime integer. An arbitrarily selected mask m is either provided to the transmitter and receiver, or constructed, at either, or both. The mask is used to create a decimated M sequence, and work backwards to define a recursion rule vector r which is associated with another primitive polynomial corresponding to the decimated M sequence. This recursion rule vector r is used to create a new feedback shift register which produces a maximum length sequence. An initialization vector i is provided to the transmitter and receiver and used as an initial load of the shift register. A selected stage of this register is exclusive-ORed ("XORed") with each bit of a plaintext message to be sent to result in cipher text. At the receiver, the same process is performed with the same mask m, and initialization vector i, to create the same recursion rule vector r, and shift register. The same stage of this shift register is then XORed with the received ciphertext message to result in the original plaintext message.

摘要： A system for communicating digital information over wires having a great deal of harmonic distortion, such as a power line, employs a transmitter which transmitter which creates a carrier wave for each of a plurality of signals to be sent. This carrier wave has frequency lobes positioned between the frequency lobes of the harmonic distortion. Each of the lobes of a single carrier signal is encoded with the same bit value during a given bit period. This signal is then mixed with any existing signal on the wire. At a remote receiver coupled to the wires, the signal is sensed, filtered, and Fourier transformed into coefficients. The signal-to-noise (S/N) ratio of each Fourier coefficient is determined by a novel S/N estimation technique. The coefficients are weighted based upon the S/N ratio estimation, and decoded, preferably by an inner product of the weighted Fourier coefficients. Additionally, the S/N ratio estimates could be time averaged before being used in the weighting and bit decoding.

摘要： Techniques are provided for using a multi-stage actuator to actuate one or more optical components of an optical head. The multi-stage actuator includes a cross-layer displacement component which actuates an optical component to change the beam focus in a displacement range corresponding to the thickness of the data layers in a holographic disk, such that a beam is impinged on the target data layer. The multi-stage actuator also includes a intra-layer focusing component which actuates the optical component in a smaller range to focus the beam on the target data position. The cross-layer displacement component and the intra-layer focusing component may each include more than one actuator. In some embodiments, the focusing component also actuates the optical component in a tilting motion to compensate for movement or imperfections of the disk during a reading or recording process.
