摘要： A receiver generates two metrics, one that is used to control the gain of an amplifier and the other that is used to determine the presence of narrowband interference, such as IMD. The two metrics may represent analog-to-digital converter (A/D) saturation and average signal strength, either of which may be used to control gain or to detect the presence of narrowband interference.

摘要： An apparatus and method generates a shaped transition between the minimum and maximum output power levels of a transmitter (500). When the transmitter is turned on a stepped transition (415) is generated at the beginning (3) of the transition region (409) followed by a shaped transition (417) to the end (6) of the transition region (409). When the transmitter (500) is turned off a shaped transition region (417') is generated at the beginning (162) of the transition region (411) followed by a stepped transition (415') at the end (3) of the transition region (411). The stepped transition (415 or 415') is generated by adjusting a voltage controlled attenuator (545) and the bias of a power amplifier (545) in the transmitter (500). The shaped transition (417 or 417') is generated by processing transmitted information through finite impulse response filters (507 or 509) before or after the time slot permitted for transmitting information.

摘要： A receiver (24) comprises a non-equalizing demodulator (48), an equalizing demodulator (46) and an output control selector (50). The non-equalizing demodulator (48) receives a modulated signal (44) and demodulates the modulated signal (44) to produce a first digital bit stream (54). The equalizing demodulator (46) receives the modulated signal (44) and equalizes and demodulates the modulated signal (44) to produce a second digital bit stream (52). The output control selector (50), coupled to the non-equalizing demodulator (48) and the equalizing demodulator (46), selectively delivers a first one of the first digital bit stream (54) and the second digital bit stream (52) for at least a predetermined period of time (30) before selectively delivering a second one of the first digital bit stream (54) and the second digital bit stream (52) responsive to a predetermined decision criterion (e.g., bit error rate 68). The first one of the first digital bit stream (54) and the second digital bit stream (52) is different from the second one of the first digital bit stream (54) and the second digital bit stream (52).

摘要： In a radiotelephone (30), a channel estimator (39) receives a time division multiple access (TDMA) information signal (31) including a synchronous codeword (44), formed of a first subset of seven sequential symbols (47) followed by a second subset of seven sequential symbols (48), followed by a data sequence (45) formed of multiple sequential symbols. The channel estimator (39) uses the first subset (47) to train, via initializing (51) and updating (52), the channel estimator to stabilize the channel estimate. The channel estimator (39) uses the second subset (48) to train, via initializing (53) and updating (54), the predictor to improve the future accuracy of the channel estimate. The channel estimator (39) then tracks (55) the channel estimate over the data sequence (45) by updating the channel estimator and the predictor over the data sequence (45), without substantially affecting the stability of the channel estimate or the future accuracy of the channel estimate.

摘要： A complex constellation point multiplier (600) multiplies a complex number by a point in a digital modulation constellation. The desired constellation point is mapped to a digital control word. The complex number is connected to multiplicand input nodes (610, 615) and the digital control word is connected to control input nodes (620, 623, 626). Via logic gates (602, 603, 605, 606, 607, 609), the control word controls switches (651-658) and simple arithmetic blocks, such as accumulators (650, 659), scaler blocks (663, 665), and negation blocks (643, 646), to generate an output complex number that is the product of the input complex number and the constellation point. This complex constellation point multiplier provides a lower size and lower power-consumption alternative to traditional complex number multipliers.

摘要： A diversity receiver (200) recovers clock information from different versions (301, 302) of a transmitted signal (106). The diversity receiver (200) receives the different versions (301, 302), converts the versions (301, 302) into samples (307, 317) via a common sampling clock (309). The receiver (200) then correlates the samples (307, 317) with like synchronization patterns and uses clock information from the received version (307 or 317) which gives the greatest correlation output signal (504, 506) for data detection in one of two detectors (323, 326). The choice of detectors (323, 326) is determined by the diversity receiver (200) by counting the total number of bit-differences output by detectors (323, 326) over a predetermined time period and comparing the total bit-differences with a number represented by a threshold signal (330).

摘要： An open-split interface includes a connector body having four leg members projecting therefrom within a single plane, the first and third legs being coaxial and the second and fourth legs being coaxial. A tubular aperture extends through the first and third legs and a second tubular aperture extends through the second and fourth legs, connecting at a juncture within the center of the connector body. A fifth leg projects from the connector body and has a third tubular aperture extending therethrough to the juncture of the first and second tubular apertures. A capillary column extends from a gas chromatograph into the third leg with its end adjacent the juncture. A flow restrictor tube extends from a mass spectrometer through the first tubular aperture in the first and third legs and into the capillary columnm end, so as to project beyond the end of the third leg within the capillary column. An annular gap between the tube and column allows excess effluent to pass to the juncture. A pair of short capillary columns extend from separate detectors into the second tubular aperture in the second and fourth legs, and are oriented with their ends spaced slightly from the first capillary column end. A sweep flow tube is mounted in the fifth leg so as to supply a helium sweep flow to the juncture.
