摘要： A wireless communications device having a fast-receive mode for measuring received signal strength indication (RSSI) enables the device to handle higher time division multiple access (TDMA) multislot classes without requiring that the device include either a second receiver or a receiver with a more advanced and expensive phase-locked loop (PLL) design. The time to complete an RSSI measurement is reduced by initiating the sampling of signal strength before the radio transceiver is fully stabilized in the downlink mode. By initiating sampling before PLL stabilization is complete, the overall time to complete an RSSI measurement is reduced sufficiently to enable scheduling of an RSSI measurement in each GSM frame.

摘要： A receiver includes a first local oscillator (LO), with a pair of in-phase and quadrature (IQ) mixers coupled to the first LO and configured to generate complex IQ signals having an IQ imbalance. The receiver also includes a second LO, with a complex mixer coupled to the second LO and configured to mix the complex IQ signals and generate intermediate frequency (IF) signals based thereon. A controller is coupled between the pair of IQ mixers and the complex mixer and configured to set the first LO and the second LO so that the complex IQ signals and an interfering signal generated due to the IQ imbalance of the complex IQ signals have a same sign and non-overlapping bands at an input of the complex mixer.

摘要： A radio receiver circuit configured to receive a radio frequency signal and produce a baseband signal as an output therefrom has a channel filter having a bandwidth, the channel filter configured to receive the baseband output at a filter input and produce a filtered output at a filter output thereof. A signal-to-noise ratio (SNR) estimator prior to or after the channel filter or both is configured to estimate a signal-to-noise ratio of the baseband signal. A filter controller is configured to receive the signal-to-noise ratio estimate and control the channel filter to adjust the bandwidth thereof in accord with the signal-to-noise ratio estimate. This process thereby assists in improving SNR after the channel filtering by varying the channel filter bandwidth. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A speed parameter or channel quality parameter are determined in a mobile device based on variation in frequency offset measurement. A higher variation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the frequency offset measurement reflects a better channel quality and a lower speed. The parameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.

摘要： A communications device, in one aspect as a portable wireless communications device, includes an in-phase modulator and power amplifier that receives a baseband I signal and modulates and amplifies the I signal. A quadrature modulator and power amplifier receives a baseband Q signal and modulates and amplifies the Q signal. A power combiner sums and outputs the I and Q signals. An I demodulator circuit receives a signal fed back from the I power amplifier and demodulates the fed back signal to produce demodulated I signals. A Q demodulator circuit receives a signal fed back from the Q power amplifier and demodulates the fed back signal to produce demodulated Q signals. A processor compares the digital, baseband I and Q signals with a demodulated I and Q signals to compensate for amplitude, frequency and phase modulation errors.
