Abstract: A system for direction of arrival determination includes a waveform detector and processing circuitry. The waveform detector includes a first pair of dielectric structures and a second pair of dielectric structures. The processing circuitry is configured to determine a direction of arrival of an electromagnetic wave incident on the waveform detector. The direction of arrival is determined based on relative power levels in the first pair of dielectric structures responsive to the electromagnetic wave and based on relative power levels in the second pair of dielectric structures responsive to the electromagnetic wave.

Abstract: Systems and methods for wireless transmission of uncompressed HDTV signals are disclosed. In one embodiment, a method for communicating an uncompressed HDTV signal over a wireless RF link includes providing a clock signal synchronized to the uncompressed HDTV signal; providing a stream of regenerated data from the uncompressed HDTV signal, the clock signal being synchronized to the stream of regenerated data; demultiplexing the stream of regenerated data using the clock signal into an I data stream and a Q data stream; modulating a carrier with the I data stream and the Q data stream; and transmitting the modulated carrier over the wireless RF link. The synchronized clock signal may be provided using a clock and data recovery (CDR) component.

In one embodiment, a method for transmitting an uncompressed HDTV signal over a wireless RF link, comprises providing a stream of regenerated data from the uncompressed HDTV signal; providing a first clock signal synchronized to said stream of regenerated data; encoding said stream of regenerated data, producing a stream of encoded data; providing a second clock signal synchronized to said stream of encoded data; demultiplexing said stream of encoded data, using said second clock signal, into an I data stream and a Q data stream; modulating a carrier with said I data stream and said Q data stream; and transmitting said carrier in a signal over the wireless RF link.

Abstract: A system for recovering and demodulating a carrier includes a carrier recovery loop and a data detector. The carrier recovery loop receives the carrier as an input and produces a recovered carrier at a frequency approximately equal to that of the carrier. The carrier recovery loop includes a downconverting mixer, a ×5 multiplier, a ×4 multiplier, and a phase locked loop. The downconverting mixer receives the carrier input, and the phase locked loop provides a VCO reference frequency through the ×5 multiplier to the downconverting mixer, which provides a frequency shifted signal. The frequency shifted signal is passed through the ×4 multiplier as input to the phase locked loop. The data detector receives the carrier and the recovered carrier as inputs and uses the recovered carrier to demodulate the carrier and detect I channel data and Q channel data.
