  • Patent number: 11637553
    Abstract: An aspect relates to an apparatus including a set of one or more receivers; a first replica circuit being a substantial replica of at least a portion of one of the set of one or more receivers; a first control circuit generates an output signal selectively coupled to an input of the first replica circuit; a second replica circuit being a substantial replica of at least a portion of one of the set of one or more receivers; a comparator including a first input coupled to a first output of the first replica circuit, a second input coupled to a second output of the second replica circuit, and an output; and a second control circuit including an input coupled to the output of the comparator, and an output coupled to the first replica circuit and to the set of one or more receivers.

  • Publication number: 20140254549
    Abstract: A multi-channel wireless device for participating on a plurality of networks. The wireless device switches from a first channel associated with a first network to a second channel associated with a second network if the wireless device has a channel dwell time on the first channel equal to or greater than a maximum channel allowance time interval for the first channel, wherein the maximum channel allowance time interval for the first channel is given by a channel switching time subtracted from a Beacon interval associated with the first network divided by the total number of networks that the wireless device is participating with.

  • Publication number: 20090197629
    Abstract: Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may receive a message sent by a second station to request reduction of interference on at least one resource. In response to receiving the message, the first station may determine a first transmit power level to use for the at least one resource based on one or more factors such as a priority metric sent in the message, the buffer size at the first station, etc. The first station may send a power decision pilot on the at least one resource at a second transmit power level determined based on the first transmit power level.

  • Patent number: 6134215
    Abstract: A system and method for enabling multiple transmitters (400) to share a single code division multiplexed (CDM) or code division multiple access (CDMA) channel using orthogonal waveforms. A set of orthogonal channelizing codes W.sub.i (t) is generated, and each transmitter (400) is allocated orthogonal channelizing codes and pseudonoise polynomials in a predetermined manner. The transmitters channelize each user signal using an orthogonal channelizing code W.sub.i (t), and spread each user signal using a pseudonoise (PN) spreading code. Each transmitter employs the same PN spreading codes and time offsets. Additionally, no one orthogonal channelizing code is assigned to more than one transmitter during the time period they are sharing a CDM channel. The spread signals are summed at each transmitter (404) prior to transmission as a composite signal. The offsets are time-precorrected (406, 510) to ensure time alignment at the receivers.
