Abstract: A method for selecting an antenna direction setting for optimum signal reception prior to channel equalization provides a set of metrics, referred to as channel quality metrics (CQM), that characterize the quality of the received signal for a given antenna setting and a generic algorithm that uses these metrics to select the antenna setting for an optimum reception. This invention utilizes five main CQMs: a Signal Strength Metric (SSM), a minimum mean squared error of a decision feedback equalizer (MMSE (DFE)) channel quality metric, a MMSE for a linear equalizer (MMSE(LE)) channel quality metric, a Spectral Flatness Metric (SFM) and an interference degradation metric (IDM).

Abstract: The specification relates to a radio frequency (RF) power detection circuit for multiple frequency bands. One embodiment of the present invention uses semiconductors as power detection sensors and as temperature compensation devices. Multiple power detection sensor current signals each develop a voltage signal across a common load resistor. Similarly, multiple temperature compensation sensor current signals each develop a voltage signal across a second common load resistor. A detector voltage and a temperature compensation voltage are then processed through common amplification circuitry, producing a signal proportional to sensed transmitted power.
