BACKGROUND
The physical layer between the satellite and the subscriber terminal operates in SIMO for the downlink and MISO for the uplink. MISO and SIMO are two degenerated cases of MIMO, where MISO has a single transmitter with multiple receivers, and SIMO has a single receiver with multiple transmitters. Generally, MIMO involves multiple transmit and/or receive engines coupled to respective antennas. In various embodiments, the antennas are configured to have independent fading with a spacing distance of ¼, ½ or a full wavelength. The system 100 includes at least one of spatial multiplexing, transmit diversity methods (e.g., space-time coding, code reuse multiple access, etc.), and/or beamforming technologies. Various embodiments can use any number or permutation of these features in implementing the system 100.
One or more of the antennas 1125 may be a cardioid antenna 1300, as illustrated in FIG. 13A. It may be configured to produce a heart-shaped upward radiation pattern 1350 illustrated in FIG. 13B, with a wider omnidirectional (in the x, y directions) radiation pattern than an unidirectional antenna. Alternatively, an antenna 1125 may be a monopole antenna 1400, as illustrated in FIG. 14A. It may be configured to produce a two lobe upward radiation pattern 1450 illustrated in FIG. 14B, with a null overhead and thus each lobe directed at an altitude of less than 90°.
In one set of embodiments, the radiation pattern for an antenna 1125 receiving and processing line-of-sight signals is intentionally configured to be directed lower on the horizon than a radiation pattern optimized to receive line-of-site signals from transmitting satellite(s) 105. In various embodiments, the directional elevation may be intentionally set to be equal to or greater than (1°, 2°, 5°, 10°, 15°, 20°, or 25°) below the optimized elevation. Alternatively, the radiation pattern may be configured in a direction equal to or greater than (1%, 2%, 5%, 10%, 15%, 20%, or 25%) below the optimized elevation. Thus, there may be various levels of gain bias that may be redirected lower on the horizon. The antennas configured according to this embodiment may be transmit and/or receive antennas.
In a corresponding set of embodiments, the radiation pattern gain for the altitude between (0°-10°, 0°-15°, 0°-20°, or 0°-25°) is intentionally increased relative to the pattern optimized for line-of-site transmission or reception. In yet another set of embodiments, the radiation pattern is divided between an emphasized satellite multipath gain and an emphasized base station multipath gain.
A device and method are described for scanning inactive antenna signals to identify better channels when dynamically switching between subsets of available antennas according to another embodiment of the invention. For example, in a receiver configured to process signals from only a subset of available antennas, the remaining (i.e., “inactive”) antennas may be scanned to identify alternatives. In one embodiment, the switching is based on measurements of received signals from the inactive antennas. The scanning may be adapted to a particular environment, for example, scanning less often for a power limited device with adequate signal strength at the active antennas. In one embodiment, a set of antennas is made up of a number of different types or configurations of antennas, some of which are more efficient for different signals or conditions.
