Polarization Diversity with Portable Devices via Wavefront Muxing Techniques

摘要

A novel terrestrial wireless communications technique for terrestrial portable terminals including hand-held mobile devices and fixed wireless instruments, utilizing a spoke-and-hub communications system, having a plurality of individual hubs and/or base-stations all in communications with the portable terminals. The portable terminals and the hubs are assigned to use incompatible polarity formats in terms of circularly polarity (CP) and linearly polarity (LP). In forward links, a signal processed by the LP ground telecommunications hubs is radiated through multiple antennas with various LP polarities to an individual CP user simultaneously. The multiple paths are organized via assignments of a plurality of polarities, frequency slots, and directions by wavefront multiplexing/demultiplexing techniques such that the same communications assets including frequency spectrum may be re-used by other users. The same polarity diversity methods can be extended to peer-to-peer communications.

1. A system for wireless communications configured to form a first communications channel and a second communications channel arranged in parallel with said first communications channel, wherein said first and second communications channels are configured to relay first data from a first portable device, wherein said first communications channel is configured to transmit a first combination associated with said first data, and said second communications channel is configured to transmit a second combination associated with said first data, wherein said first communications channel utilizes a polarization different from one said second communications channel utilizes.
