摘要： A method of peak suppression includes buffering (401) a plurality of modulation samples, yielding a plurality of buffered samples. A peak sample is determined (403) from among the plurality of buffered samples. A complex scaling value is determined (405). A plurality of waveform values is established (407). The plurality of waveform values is multiplied (409) by the complex scaling value, yielding a plurality of alteration values. The plurality of alteration values is combined (411) with the plurality of buffered samples, yielding a plurality of peak suppressed samples.

摘要： This disclosure addresses providing gigabit-rate data transmission over wireless radio links, using carrier frequencies in the millimeter-wave range (>30 GHz). More specifically, a circuit for detection of amplitude-shift keyed (ASK) or other amplitude modulations (AM) which can be easily incorporated into an integrated circuit receiver system is described, making the receiver capable of supporting both complex IQ modulation schemes and simpler, non-coherent on-off or multiple-level keying signals. Several novel radio architectures are also described which, with the addition of a frequency discriminator network, have the capability of handling frequency shift keyed (FSK) or other frequency modulations (FM), as well as AM and complex IQ modulation schemes. These radio architectures support this wide variety of modulations by efficiently sharing detector hardware components. The architecture for supporting both quadrature down-conversion and ASK/AM is described first, followed by the ASK/AM detector circuit details, then the AM-FM detector architecture, and finally the most general AM-FM/IQ demodulator system concept and the FSK/FM detector circuit details.

摘要： An apparatus and method to control signal phase in a radio device includes a phase rotator configured to control a phase of a local oscillator. A phase error determination module is configured to determine phase error information based on received in-phase (I) and quadrature (Q) (IQ) signal values. A phase correction module is configured to derive from the received IQ signal values a correction signal and apply the correction signal to the phase rotator in a path of the local oscillator.
