Latest Patents
Chalkley's latest patents include a "Point to multipoint communication system with subsectored upstream antennas." This innovative system allows a base station to broadcast the same frequency band signals over multiple sectors of a given node. The design incorporates a plurality of channel receivers for each sector and multiple antennas, which are selectively coupled to the channel receivers. The subsector antennas are strategically offset to provide different coverage over the node.
Another significant patent is the "Global Position System receiver." This GPS receiver features an RF converter and quadrature digitizer implemented in hardware, along with a signal processor that includes a computer, code generator, and preprocessor. The preprocessor controls the code generator to provide early, prompt, and late digital signals for tracking code phase, carrier phase/frequency, and signal amplitude. This innovative structure eliminates the need for numerically controlled oscillators while maintaining accurate performance.
