Abstract: This invention describes a method by which Broadband Spectrum Analysis can be performed in the RF and Microwave frequency range with significantly higher speed, accuracy, and flexibility than existing RF and Microwave Spectrum Analyzers. This is done by eliminating the need for the filtering of the incoming signal, a process called preselection that needs to track in frequency with the scanning local oscillator in the instrument. By eliminating this requirement, this invention makes possible the identification and analysis of very broadband signals in a single sweep using an Adaptive Sweep Methodology and a Simultaneous Sweep capability that the present invention makes possible.

Abstract: Various wireless precoding systems and methods are presented. In some embodiments, a wireless transmitter comprises an antenna precoding block, a transform block, and multiple transmit antennas. The antenna precoding block receives frequency coefficients from multiple data streams and distributes the frequency coefficients across multiple transmit signals in accordance with frequency-dependent matrices. The transform block transforms the preceded frequency coefficients into multiple time domain transmit signals to be transmitted by the multiple antennas. The frequency coefficients from multiple data streams may be partitioned into tone groups, and all the frequency coefficients from a given tone group may be redistributed in accordance with a single matrix for that tone group. In some implementations, the frequency coefficients within a tone group for a given data stream may also be precoded. In some alternative embodiments, tone group preceding may be employed in a single channel system.

Abstract: This invention describes a method by which the output power of a circuit or system at any point can be efficiently and cost effectively sampled in a simple and broadband fashion for processing in a closed loop system for applications such as power level control in very broadband circuits. A divider circuit consisting of a selection of passive lumped elements is used to create a very broadband means of sampling the RF power level at any point in a transmission line. Unlike prior art schemes of this nature, this circuit does not rely upon extremely accurate element values and minimization of parasitic reactances. Used in conjunction with a balanced detector-logarithmic or other amplifier combination this invention result in a very broadband low cost simplified realization of the traditional costly bandwidth limited directional coupler-detector combination.
