摘要： The modulation format of a data block (frame) received from a servicing base station by a wireless terminal in a cellular wireless communication system is identified. This involves first receiving several radio frequency (RF) bursts of one data block (frame) from the servicing base station. The RF burst carries a number of modulated symbols. The training sequence is extracted from the RF burst and is made of a number of modulated symbols. The training sequences are first processed assuming a first modulation format to produce a first accumulated channel energy. Then, the training sequences are processed assuming a second modulation format to produce a second accumulated channel energy. The first and second accumulated channel energies are compared to determine which accumulated channel energy is greater. The modulation format of the data block is identified as the modulation format corresponding to the greater accumulated channel energy.

摘要： Aspects of a method and system for signal phase variation detection in communication systems are presented. Aspects of the system may enable detection of phase change between a current received symbol, and one or more previous received symbols. Based on the phase change a channel estimation filter bandwidth may be selected for despreading and/or descrambling one or more subsequent received symbols. In addition, a decision may be made as to whether the subsequent received symbols are to be received based on a closed loop system, or based on an open loop system.

摘要： Aspects of a method and system for multimode DC offset compensation are presented. Aspects of the system may include accumulating a selected number of signal samples, determining an average of the accumulated signal samples, and keeping a running total of the average for use feedback signal generation. The signal samples may be, for example, samples of WCDMA signals. By keeping track of the signal offset error, the signal offset error, or residual DC, may be determined. For example the signal offset error may comprise a DC component and/or a sinusoidal component. The number of signal samples to accumulate for the average may be based on the signal offset error.

摘要： Various aspects of a method and system for adaptive multi rate and measurements adaptation may include a processor that enables computation of at least one signal level measurement for at least one received signal. The processor may enable cancelling of interfering signals received in addition to the received signal based on processing of a received bit sequence using a first burst process operation (BP) in a first decoding algorithm that utilizes SAIC operations. The processor may also enable cancelling of noise signals received in addition to the received signal based on processing the received bit sequence using a second BP operation that utilizes redundancy and imposes a physical constraint during decoding. The processor may also enable adjustment of the computed at least one signal level measurement.

摘要： A baseband processing module includes TX processing components, a processor, memory, an RX interface, and a cell searcher module. The TX processing components receive outbound data, process the outbound data to produce a baseband TX signal, and output the baseband TX signal to a RF front end of the RF transceiver. The RX interface receives a baseband RX signal from the RF front end carrying a WCDMA signal. The cell searcher module receives the baseband RX signal, scans for WCDMA energy within the baseband RX signal, acquires slot synchronization to the WCDMA signal based upon correlation with a Primary Synchronization Channel (PSCH) of the WCDMA signal, acquires frame synchronization to, and identify a code group of, the WCDMA signal based upon correlation with a Secondary Synchronization Channel (SSCH) of the WCDMA signal, and identifies the scrambling code of the WCDMA signal based upon correlation with a Common Pilot Channel (CPICH) of the WCDMA signal.

摘要： 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. 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. This results in alternate soft samples or decisions which in turn may be converted to alternate data bits. The alternate soft samples are processed with the de-interleaver and channel decoder, where the combination is operable to produce an alternate decoded frame of data bits from the alternate soft samples. This allows interfering signals to be cancelled and more accurate processing of the received RF bursts to occur.
