Patents by Inventor Hsiang-Ling Li

Hsiang-Ling Li 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: 8787285
    Abstract: A radio frequency (RF) transceiver includes an RF section including an RF receiver operable to convert a received RF signal into inbound data and an RF transmitter to convert outbound data into a transmit signal in accordance with a local area network protocol. A processing module configures the RF section for communication with a first remote device via a first frequency channel of the local area network protocol and configures the RF section for communication with a second remote device via a second frequency channel of the local area network protocol to maintain simultaneous association with both the first remote device and the second remote device.
    Type: Grant

    Date of Patent: July 22, 2014
    Assignee: Broadcom Corporation

  • Patent number: 6754283
    Abstract: A three-stage four-dimensional encoding system and method for DMT-based transceivers includes a first stage where a parallel shifter shifts three bits of input data bits from a shadow register into a holding register. Next, a convolutional encoder generates encoded bits v1, v0, w1 and w0, using the three bits in the holding register. The encoded bits w1 and w0 may be registered as w1′ and w0′ for later use. In the second stage, the encoded bits v1 and v0 are provided to the inputs of the parallel shifter for parallel parsing of bits for the first tone of a pair of tones of DMT and the number of bits needed for the first tone are parallel shifted to the holding register. The bits in the holding register are then mapped by a constellation mapper into a constellation point.
