Abstract: A baseband processing module of a wireless terminal includes a Turbo decoding module. The Turbo decoding module decodes a Turbo code word to produce one or more Media Access Control (MAC) packet(s) carried by the turbo decode word. Each MAC packet includes a MAC packet header and the MAC packet payload, which carries one or more Radio Link Control (RLC) Packet Data Units (PDUs). The Turbo decoding module decodes the MAC packet header to determine boundaries of the PDUs carried in the MAC packet payload. The Turbo decoding module decodes RLC PDU headers and RLC PDU payloads of the RLC PDUs. The Turbo decoding module writes the decoded MAC packet header, the decoded RLC PDU headers, and the decoded RLC PDU payloads to memory in a word-aligned format. The Turbo decoding module may also operate in various other Turbo decoding modes.

Abstract: Aspects of a method and system for CQI based adaptive diagonal loading for DMI-EQ in HSDPA receivers. A HSDPA enabled handset may comprise a minimum-mean-square (MMSE)-based direct matrix inversion (DMI) equalizer (DMI-EQ) for an advanced signal processing. The DMI-EQ may receive HSDPA signal in consecutive transmission time intervals (TTIs). A diagonal loaded DMI may be used for a robust solution of equalizer weights. The DMI diagonal loading coefficients may be determined based on the CQI value of the current TTI and apply to the DMI-EQ for the next TTI. The determined CQI may be derived from SNR information estimated via a reference signal in the received signal. A look-up table mechanism is provided to select a set of DMI diagonal coefficients for a determined CQI and a particular modulation type. The look-up table may comprise mappings between the CQI for a particular modulation type and various DMI diagonal coefficients.

Abstract: In a method and system for an adaptive automatic gain control (AGC) reference for HSDPA and WCDMA, A RF receiver, comprising a RF front-end, may receive a signal comprising a pilot signal via WCDMA or HSDPA. The operation mode of the RF front-end of the RF receiver may be determined based on the received signal components such as a HS-PDCH, a HS-SCCH, and/or a CPICH. The received signal strength information (RSSI) of the received signal may be determined from the output of a matched filter within the RF receiver. A true RSSI, which may be indicated by the received signal code power (RSCP), may be determined based on the pilot symbols over the CPICH. The operation mode determined for the receiver's RF front-end, the determined RSSI, and the determined CPICH_RSCP, may be provided as inputs to an automatic-gain-control (AGC) loop or circuit within the receiver front-end.

Abstract: Aspects of a method and system for adaptive quantization steps for HS-SCCH decoding using average CQI are provided. A HS-SCCH in a received HSDPA signal may be adaptively quantized before HS-SCCH decoding occurs. Quantization information may be determined based on a CQI value associated with the HS-PDSCH. A preferred soft bit precision and quantization geometry, which associated with the quantization information, for the given soft bit precision may be determined based on the CQI value. The received HS-SCCH data may be truncated with the determined soft bit precision in the determined quantization geometry, accordingly. A look-up table, which may comprise the mappings between CQI and quantization step information, may be used for selecting quantization step sizes in HS-SCCH quantizing in order to, for example, lower the complexity in HS-SCCH quantizing.

Abstract: One or more circuits in a mobile phone may be utilized for up sampling two or more audio signals to a same data sampling rate. Each audio signal, such as digital audio, voice, and polyringer, for example, may be received at one of a plurality of data sampling rates and one or more of the following wireless standards: WCDMA, HSDPA, GSM, GPRS, EDGE, and/or Bluetooth. Audio signals may be equalized and/or compensated with an FIR filter before up sampling or with an IIR filter to reduce overall processing latency. Multiple half-band interpolation operations may perform the up sampling. The first half-band filter may be replaced by an IIR filter to reduce overall processing latency. A gain of the up-sampled data may be adjusted to reduce noise effects. The channels of the up-sampled audio signals may be mixed and later further up sampled for subsequent communication to an output device.

Abstract: A system and method for acquiring a transmitted spread-spectrum signal uses a matched filter configuration that is preferably employed as a Stage 2 filter in the second phase of an initial signal acquisition procedure performed in the receiver. In operation, a Stage 1 filter matches a sequence which is repeated a number of times according to a second sequence within a secondary synchronization sub-channel of the spread-spectrum signal. The Stage 2 filter of the invention then filters the output of the Stage 1 filter in order to recover a secondary synchronization code. The Stage 2 filters the output of the Stage 1 filter using three matched filters of its own. The first and second filters sample different taps of a sequence output from the Stage 1 filter. The third filter samples a predetermined number of taps overlapping taps for the first and second filters in a way that resolves ambiguities with respect to the identification of the sequence.

Abstract: Apparatus and method to provide unified STTD/CLTD dedicated pilot processing in a wireless receiver. The technique allows different set of parameters to be introduced to a same processing module to process STTD and CLTD diversity signals to recover a pilot signal. Introducing another set of parameters to the processing module also allows processing of a non-diversity signal to recover a pilot. The unified processing of STTD/CLTD signals is achieved by converting STTD/CLTD pilot bits as Hadamard-like bits and processing these bits along with orthogonal pilot bits which are encoded as Hadamard encoded bits.

Abstract: A method to adapt channel quality indicator (CQI) reports from user equipment (UE) is provided. This involves first determining the presence of a high-speed shared control channel (HS-SCCH) signal. An estimated signal to noise ratio (SNR) is also determined. Next an SNR correction based on the presence or lack thereof of the HS-SCCH signal and the CRC checks for HS-SCCH and HS-DSCH signals are determined and applied to the estimated SNR. The CQI report is then generated based on the corrected estimated SNR. This CQI report which takes into account a corrected estimated SNR may then be used to adjust the HS-SCCH signal in an HSDPA telephony system.
