摘要： Aspects of a method and system for dual voice path processing in an audio CODEC may enable selecting two or more signals received via one or more audio input devices, and filtering and down-sampling each of the selected signals via two or more signal processing branches. Furthermore, an output sample rate of each of the signal processing branches may be configured independently. The signal processing branches may each comprise one or more IIR filters with configurable coefficients and one or more cascaded-integrate-comb (CIC) decimation filters having a configurable decimation ratio. A first of the selected signals, may be filtered and/or down-sampled to generate a signal having a first, lower, sample rate, and a second of the signals may be filtered and/or down-sampled to generate a signal having a second, higher, sample rate. One or more post-processing algorithms such as audio beamforming may also be performed on the selected signals.

摘要： Apparatus and method to process a pilot channel and a synchronization channel to obtain a combined noise estimate of the pilot channel and the synchronization channel that is synchronized to the pilot channel. The combined noise estimation is processed to determine a first noise component for a period when both the pilot channel and the synchronization channel are present. Then, the combined noise estimate is processed to determine a second noise component for a period when only the pilot channel is present. Next, the second noise component is subtracted from the first noise component to derive a noise estimation for the synchronization channel. The technique may be applied to the Common Pilot Channel (CPICH), and the Synchronization Channel (SCH) defined in a 3rd Generation Partnership Project standard specification.

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 UMTS HSDPA Shared Control Channel processing may include calculating at a receiver, for each one of a plurality of control channels, a quality metric derived from at least one Viterbi Decoder state metric. A control channel may be selected on the basis of the quality metrics, where the quality metric is selected that provides maximum confidence. The selected control channel may be chosen if its corresponding 3GPP metric is greater than a specified threshold, where the threshold is a design parameter. A validity of a selected control channel may be determined based on consistency and a CRC, where the CRC may be derived from decoding a sub-frame. The calculating and selecting may be done for a first slot of a sub-frame for High-Speed Shared Control Channels.

摘要： Methods and systems for audio CODEC voice ADC processing are disclosed. Aspects of one method may include using a decimating filter that may be enabled to generate 13 MHz, 9-level digital output signal from a 26 MHz, 3-level digital input signal. The 13 MHz, 9-level digital output signal may be processed for RF transmission, for audio output to an output device, and/or utilized for testing by a test fixture, for example. The 13 MHz, 9-level digital output signal may be further processed to generate a 6.5 MHz, 33-level digital signal. The 6.5 MHz, 33-level digital signal may be converted to an analog signal, and processed for audio output and/or testing. The 13 MHz, 9-level digital output signal may also be processed to generate a 40 KHz, 17-bit digital signal, which may be communicated to a test equipment or further processed for RF transmission.

摘要： A system for processing radio frequency (RF) signals includes a searcher and a plurality of Cluster Path Processor (CPPs). The searcher detects a maximum signal energy level and position of at least one of a plurality of individual distinct path signals in a signal cluster of a first information signal, wherein at least a portion of the plurality of individual distinct path signals is received within a duration of a corresponding delay spread. The sampling position is used as a starting sampling location by the plurality of CPPs, including a first information signal CPP and a second information signal CPP. Fine sampling positions of the plurality of CPPs are based upon channel energy estimates for the plurality of individual distinct path signals. CPP outputs are employed to produce channel estimates, which are themselves used in subsequent equalization operations. Sampling positions may change over time in order to satisfy alignment criteria.

摘要： In a 3G cellular network, a Reverse Link Channel Quality Indicator Channel (R-CQICH) may be transmitted on a reverse link to support forward link high-speed data transmissions. Accordingly, the R-CQICH may be utilized to track the quality of the signal path between the wireless unit and the base station. The base station may include a CQI component that utilizes a received Channel Quality Indicator (CQI) signal from the wireless unit to generate CQI quality metrics based on the quality of the received signal. Also, the CQI quality metrics may be compared to different thresholds to adjust various system configurations in the base station. The base station may also provide feedback to the wireless unit with the updated system configurations. This technique allows CQI quality metrics to be utilized to adjust system configurations dynamically and enhance the operation of a wireless system.
