  • Patent number: 8457264
    Abstract: A radio receiver includes a first diversity antenna structure, a second diversity antenna structure, a first RF receiver section, a second RF receiver section, a combining module, and a baseband processing module. The first diversity antenna structure provides the received inbound RF signals from one of the plurality of first antennas based on a first antenna selection signal to produce first received inbound RF signals. The second diversity antenna structure provides the received inbound RF signals from one of the plurality of second antennas based on a second antenna selection signal to produce second received inbound RF signals. The first and second RF receiver sections are operably coupled to convert the first and second received inbound RF signals into first and second inbound baseband signals, respectively. The combining module combines the first and second inbound baseband signals to produce inbound baseband signals.

  • Patent number: 8355715
    Abstract: An encoded signal is modulated to produce a first radio frequency (RF) signal that is transmitted to a client module over a first transceiver channel when a first transceiver module is in a transceive mode. A channel scan is performed when the first transceiver module is in a scan mode. The encoded signal is modulated to produce a second RF signal and that is transmitted over a second transceiver channel when a second transceiver module is in a transceive mode.

  • Patent number: 7792182
    Abstract: A method and apparatus for adjusting symbol timing and/or symbol interval range of a receive burst of data within a radio receiver include processing that begins by receiving a radio frequency signal that includes bursts of data. The process then continues by determining a frequency offset for the burst of data based on a difference between the transmitter processing rate and a receiver processing rate. The processing then continues by determining a symbol timing offset and/or a symbol interval range offset based on the frequency offset. The process then proceeds by adjusting the initial symbol positioning and/or the symbol interval range offset of a burst of data based on the symbol timing offset.

  • Patent number: 7725807
    Abstract: A method for field error checking begins by decoding a predetermined pattern of a field of a frame to produce a decoded pattern. The method continues by determining, for the decoded pattern, a path metric distance of a predetermined state of a plurality of states of the decoding. The method continues by comparing the path metric distance with an excepted path metric distance for the predetermined state. The method continues by indicating a field error when the path metric distance compares unfavorably with the excepted path metric distance.

  • Patent number: 7466775
    Abstract: A method for detecting validity of a received signal begins by performing an auto-correlation on the received signal to produce an auto-correlation resultant. The process continues by performing a cross-correlation on the receive signal with a reference signal to produce a cross-correlation resultant. The process then continues by mathematically relating the auto-correlation resultant with the cross-correlation resultant to produce a mathematical correlation relationship. The process then proceeds by interpreting the mathematical correlation relationship to indicate whether the receive signal is valid or not.

  • Patent number: 7280588
    Abstract: A correlation module includes a plurality of first functional modules, a plurality of second functional modules, a plurality of function adjust modules, a summation module, a correlation value register, and a correlation evaluation module. The plurality of first functional modules is operably coupled to perform a first function upon a first corresponding pipelined data element to produce a first corresponding value. The plurality of second functional modules is operably coupled to perform a second function upon a second corresponding pipelined data element to produce a second corresponding value. The plurality of function adjust modules is operably coupled to selected ones of the plurality of first functional modules and to selected ones of the plurality of second functional modules. The summation module is operably coupled to sum the plurality of first corresponding values, the plurality of second corresponding values, and a previous correlation value to produce a current correlation value.

  • Patent number: 7106715
    Abstract: A system is provided for transmitting data to a plurality of devices. A data source receives data from a video broadcasting source, such as a digital television provides, through a data cable. The data source identifies devices to receive particular sets of data, such as particular programs, from the data cable. The data source identifies particular settings for transmitting to particular devices. The data source adjusts a transmission power to a first device to efficiently provide data reliably to the first device. The data source can assign more or less power for transmitting data to the first device. The data source provides data to the source device using a first data channel. The data source provides data to a second device using a second data channel. The data source receives acknowledgements and control information from the first device and the second device using the second data channel.

  • Patent number: 7072632
    Abstract: A valid signal may be detected by initializing gain settings of the receiver section. The processing then continues by measuring received signal strength of a signal received by the receiver section to produce a 1st received signal strength indication (RSSI). The processing continues by adjusting the gain setting of the receiver section such that the 1st received signal strength indication is a predetermined offset less than a signal strength threshold. The process then continues by measuring the received signal strength of the gain adjusted representation of the signal to produce a 2nd received signal strength indication. The processing continues by appending a 2nd offset to the 2nd received signal strength value to produce an adjusted received signal strength indication value when the 2nd received signal strength value drifts from the signal strength threshold less the predetermined offset.
