Techniques and designs for tunable and dynamically stabilized a laser wavelength in various lasers, including fiber lasers and actively mode-locked lasers. In an actively mode-locked laser, a dynamic wavelength tuning control and a dynamic cavity length control are implemented to maintain mode locking during tuning of the laser wavelength.

The present invention provides a multi-branch equalizer processing module operable to cancel interference associated with received radio frequency (RF) burst(s). This multi-branch equalizer processing module includes both a first equalizer processing branch and a second equalizer processing branch. The first equalizer processing branch is operable to be trained based upon known training sequences and equalize the received RF burst. This results in soft samples or decisions which in turn may be converted to data bits. The soft samples are processed with a de-interleaver and channel decoder, where the combination is operable to produce a decoded frame of data bits from the soft samples. A re-encoder may re-encode the decoded frame to produce re-encoded or at least partially re-encoded data bits. An interleaver then processes the at least partially re-encoded data bits to produce and at least partially re-encoded burst. The second equalizer processing branch uses the at least partially re-encoded data bits to train linear equalizer(s) within-the second equalizer processing branch.

The present invention provides an equalizer processing module within a wireless terminal having an equalizer interface that receives an incoming baseband signal from a baseband processor operably coupled to the equalizer processing module and outputs soft decisions. A processor or advanced reduced instruction set computer (RISC) machine (ARM) couples to the equalizer interface while an equalizer accelerator module operably couples to the processor or ARM. Processing of the incoming baseband signal to produce soft decisions is performed by the combination of the processor and equalizer accelerator module. A sample capture buffer and an equalizer output buffer which may or may not be within the equalizer processing module allow data to be sampled and serves as the input and output for the equalizer processing module. This equalizer accelerator may specifically perform compute intensive operations such as Trellis computations for MAP equalization or MLSE equalization.

In an audio processing device, a method and system for improved CODEC with polyringer are provided. An audio CODEC may comprise an audio ADC, an audio DAC, and a sidetone generator. Data from an external microphone may be processed by an audio ADC and may be sent to a processor that may be adapted to perform digital signal processing operations. The audio DAC may receive from the processor digital audio and polyphonic ringer data and may process the digital audio and polyphonic ringer data through separate digital filters and digital interpolators. The audio DAC may add the processed digital audio and polyphonic ringer data before analog conversion. The audio DAC may perform analog conversion by utilizing a delta-sigma modulator, a current-based DAC, and a switched-capacitor filter. The converted data may be filtered with an RC filter and may be utilized to drive an external speaker or earpiece.

Circuits and methods for modulators that receive symbols, and provide I (incident, or in-phase) and Q (quadrature) component values from a look-up table for subsequent filtering and digital-to-analog conversion. The I and Q component values depend on frequency correction and time index signals such that operating frequency differences between a handset and base station are compensated for, and the transmitted symbols are continuously phase shifted by 3π/8 radians.

Equalizer training method using re-encoded bits and known training sequences. A multi-branch equalizer processing module is operable to cancel interference associated with received radio frequency (RF) burst(s) (e. g. , using at least a first equalizer processing branch and a second equalizer processing branch). The first equalizer processing branch is operable to be trained based upon known training sequences and to equalize the received RF burst. The second equalizer processing branch uses at least partially re-encoded data bits to train linear equalizer(s) within the second equalizer processing branch. A buffer may initially store the received RF burst(s), which are retrieved and equalized by the second equalizer processing branch once the linear equalizer(s) are trained. The cooperation operation of these and other various components allows interfering signals to be cancelled and for more accurate processing of the received RF bursts to occur.
