Polarization diversity with portable devices via wavefront muxing techniques
First Claim
1. A system for wireless communications comprising:
- a first circularly-polarized (CP) portable device;
a horizontally-polarized (HP) communications channel; and
a vertically-polarized (VP) communications channel arranged in parallel with said horizontally-polarized (HP) communications channel, wherein said horizontally-polarized (HP) and vertically-polarized (VP) communications channels are configured to relay first data from said first circularly-polarized (CP) portable device at a common frequency slot, wherein said horizontally-polarized (HP) communications channel is configured to transmit a first combination associated with said first data, and said vertically-polarized (VP) communications channel is configured to transmit a second combination associated with said first data.

Abstract
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.
