Abstract: A method and apparatus for correcting direct current (DC) offset errors of a received signal in a direct conversion receiver (DCR) are provided. DC offset correction algorithms are incorporated into the DCR, each algorithm being optimized for a particular receive signal operating environment. The DC offset correction algorithms remove DC offset errors in baseband In-phase and Quadrature-phase signals received within the direct conversion receiver baseband signal path. Individual DC offset correction algorithms are selected for use as determined by a signal quality estimator component. A DC offset correction component of the direct conversion receiver determines an appropriate DC offset correction algorithm suited for a particular operating environment. A criterion for a signal quality estimate is set to control transitioning between DCOC algorithms. A dual threshold strategy may be adopted to transition between one DC offset correction algorithm and another DC offset correction algorithm to provide hysteresis.

Abstract: A method and apparatus for improving signal reception in a receiver (100) by performing all-channel and/or on-channel estimations on a received signal so as to predict future RF environments. The prediction is achieved through the use of one or more detector systems (122, 124) positioned to sample and detect predetermined signal metrics of the received signal (103) prior to analog-to-digital conversion (112) and subsequent post-processing (114). Future estimations of the channel condition are thus generated prior to the arrival of the actual samples (115) at a controller section (116). The detectors (122, 124) provide triggers (123, 125) to the controller (116) so that active stages (130) within the receiver (100) can be adjusted and scaled as needed via a serial port interface (SPI) (126) based on signal conditions.

Abstract: A method for maximizing intermodulation interference protection during a handoff between radio cell sites (300) includes scanning a plurality of radio channels (302) and measuring the signal power (307, 315) for at least one of the radio channels. One or more receiver attenuators (313) are then set based on the detection of intermodulation (IM) interference of the measured channel. The attenuators are then scaled (311) based on the degree of IM interference. If the attenuators cannot mitigate this interference below some predetermined level, the radio channel is changed (321) and the process begins again to ensure a high quality of communication with a cell site.

Abstract: A method of detecting an on-channel signal and synchronizing signal detection with correcting for DC offset errors in a direct conversion receiver is presented. A received signal is digitized, and a state machine operates to detect the presence of an on-channel signal. If the signal is not detected, a mixed mode training sequence is initiated in which the DC offset errors in both an analog and digital received signal path are corrected. While training, processing of the digitized samples by a digital signal processor and a host controller is suspended (while they are put into battery save mode) and the gain provided to subsequently received signals is minimized. The DC offset correction circuitry is bypassed and put into battery save mode at predetermined periods when DC offset correction is not performed.

Abstract: A radio receiver (300) having a multi-state variable threshold automatic gain control (AGC) for fast channel scanning acquisition includes an amplifier (303) having an automatic gain control (AGC) for controlling the gain of a receiver analog signal. An analog-to-digital converter (ADC) (311) is used for converting the receiving analog signal to a digital signal while a digital signal processor (DSP) (325) operates to process the digital signal. A signal magnitude estimator (315) in an AGC controller (313) provides a signal strength estimate of the received signal. The AGC controller (313 ) then sets the receiver amplifier (303) for an open-loop AGC operational mode and sets a first threshold for triggering an interrupt service request (ISR). This ISR is provided the DSP (325) and the host processor (327) if a radio frequency (RF) signal is detected above a first threshold during a priority scan of a priority channel to minimize interruptions in audio during priority scan.
