摘要： Reverse link data rate indications in wireless communication systems are defined with low identification overhead. Existence of a pilot signal is leveraged in order to reduce the overhead for identifying and selecting the reverse link data rate. At least two distinguishable pilot signals are defined, in which, based on the particular pilot signal present in the transmitted frame, at least one rate set from the multiple available rate sets can be determined. Reverse rate information in the transmitted frame is then used to identify which specific data rate within the determined rate set is used. Based on the identified data rate, the receiver may then decode the payload data in the transmitted frame.

摘要： In a synchronous application to control forward link (FL) data rates in a satellite system, user equipment (UE) repeatedly transmits a quality control measurement (QCM) index during a QCM period. During this QCM period, the data rate cannot change. The associated satellite transmits at a new rate corresponding to the QCM index. The UE knows that it will begin receiving new data at the new rate after a QCM delay. In an asynchronous application, a satellite transmits a rate change signal over a FL rate indication channel (RICH). A UE monitors the FL RICH for this signal. When the signal quality is to be low, the satellite sends only a single bit of the QCM index over a first orthogonal channel. When the signal quality is not low, the satellite transmits each bit of the QCM index in a separate orthogonal channel of the FL RICH.

摘要： A hybrid satellite-mesh network including a ground segment, a mobile segment and a satellite segment provides high bandwidth communication between mobile platforms and the Internet. The satellite segment is used only when mesh network communication links between mobile segment nodes and ground segment nodes are unavailable. Mobile segment nodes can function in either an access terminal mode or an access point mode to communicate with other mobile segment nodes according to a routing algorithm in a mesh portion of the network. Mobile segment nodes employ adaptive frequency reuse, link level date rate adaptation, link level power control and adaptive beam forming antennas.

摘要： An apparatus includes an azimuth adjuster coupled between a motor and a directional antenna. Motor rotation causes the azimuth adjuster to rotate the antenna about an azimuthal axis. The motor rotation also causes an elevation adjuster to rotate, which causes a screw mechanism to modify an elevation angle by pivoting the antenna about an elevational axis. To aim the directional antenna, a body-direction vector of a movable body with the antenna attached thereto is determined. Based on an elevational relationship between the body-direction vector and a satellite-direction vector, the elevation adjuster modifies the elevation angle of the antenna by rotating the motor to achieve full-turn amounts to pivot the antenna. The azimuth adjuster modifies an azimuth angle of the antenna based on an azimuthal relationship between the body- direction vector and the satellite-direction vector by rotating the motor to achieve partial- turn amounts of the antenna.

摘要： A method an apparatus for selecting a forward link and return link data rate for a constant power, variable data rate two-way, mobile satellite communications link. The forward link and return link signal strength (in the form of carrier power to noise power spectral density ratio) is measured, cataloged, and the values are used for the data rate selection. In addition, a ping can be sent by the network operation center to the mobile unit and the response to the ping is used for updating the information of both forward link and return link signal strength, so the chance of wrong data rate selection can be reduced. Multiple re-transmission attempts combined with gradually increased re-transmission margin ensures the proper data rate decision can be eventually achieved even with occasionally inaccurate signal strength information.

摘要： A method of pre-coding MIMO signals for concurrent transmission over a plurality of twisted pairs is disclosed. A channel estimation is determined based, at least in part, on interference attributable to a number 2N of conductors that form N twisted pairs, wherein N is an integer greater than or equal to 2. For some embodiments, a set of test signals may be transmitted, via the N twisted pairs, from a first device to a second device, and the channel estimation may be received, based on the set of test signals, from the second device. At least 2N-1 data streams are pre-coded, based on the channel estimation, to be concurrently transmitted over the N twisted pairs. For some embodiments, 2N test signals may be pre-coded to be concurrently transmitted over the N twisted pairs.

摘要： A system and method for determining a signal propagation delay between a transmitter and a receiver, and for adjusting a transmission time based on the propagation delay. A central station inserts a marker into a transmitted signal at a time corresponding to a received timing signal. The MCT receives the signal from the central station and determines a time difference between receipt of the marker and the detection of the time interval event. A transmission by the MCT is adjusted by an amount of time proportional to the time difference.
