Severine E. Catreux-Erceg has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9042350
    Abstract: A channel receiver operable to implement fractional dedicated physical channel (F-DPCH) for high-speed data packet access is provided. A received RF signal is processed to produce a set of soft symbol outputs. The receiver detects whether transmit power control (TPC) command bits are present in the set of soft symbol outputs. The TPC command bits are conveyed with the RF signal over non-dedicated pilot bits in the processed baseband signal. When TPC command bits are detected, the set of soft symbol outputs are processed to produce estimated TPC command bits. A TPC quality estimate is generated based on the estimated TPC command bits. A signal-to-interference ratio for the WCDMA dedicated physical channel is adjusted based upon a comparison of the TPC quality estimate with a TPC quality target to effect F-DPCH power control.

  • Patent number: 8437315
    Abstract: A downlink channel receiver operable to implement fractional dedicated physical channel (F-DPCH) processing within a Rake receiver structure is provided. The downlink channel receiver includes a receiver, a baseband processing block, a WCDMA processing block, wherein F-DPCH processing is divided between a plurality of hardware processing blocks and a plurality of firmware (FW) processing blocks. The receiver is operable to convert a radio frequency (RF) signal to a baseband signal. The baseband processing block operable to processes and provides the baseband signal to the WCDMA processing block. F-DPCH processing is divided between the plurality of hardware processing blocks and plurality of firmware (FW) processing blocks.

  • Patent number: 8014438
    Abstract: A method to process DP bits within a WCDMA receiver where a noise estimation that may be implemented within hardware is provided for improved flexibility and performance. DPCH pilot symbols are received, quantized, channel compensated and combined. The computation of an SNR estimate based on the combined DPCH pilot symbols is provided. Noise estimation is used as part of the SNR estimation of the DP bits (used for downlink power control). This method does not rely on the assumption that the channel is constant over the DP field, while prior methods did.
