Abstract: A method includes receiving in a communication terminal a signal, which is transmitted in multiple links and which includes a control channel transmitted in an assigned sequence of the links. One or more candidate sequences of the links, which are likely to be the assigned sequence, are identified. For at least, one candidate sequence, a verification is made whether the candidate sequence is the assigned sequence, by re-encoding decoded bits of the candidate sequence to produce regenerated symbols and comparing the regenerated symbols to respective received symbols from which the decoded bits were decoded. The control channel is decoded from the candidate sequence in response to verifying that the candidate sequence is the assigned sequence.

Abstract: A method includes, in a mobile communication terminal, receiving signals in a frequency band. One or more lists of entries are generated based on the received signals, each entry specifying a respective frequency channel suspected of containing a carrier of a respective Radio Access Technology (RAT). At least some of the entries are scanned in accordance with a scanning order that alternates from a first RAT to a second RAT before scanning all the entries of the first RAT. For each scanned entry, detection is made whether the respective frequency channel actually contains the carrier of the respective RAT. The detection of the carriers in the frequency band is output.

Abstract: A method includes receiving a signal in a communication terminal. A power spectral density, which the signal would have under full-load conditions of a transmitter transmitting the signal, is estimated based on the received signal. An operation is performed in the communication terminal using the estimated power spectral density.

Abstract: Apparatuses and methods are provided for generating a plurality of redundancy versions using various rate matching algorithms. In some embodiments, a rate matcher is provided that allocates systematic and parity bits to the redundancy versions in a manner that allows all of these bits to be transmitted in at least one redundancy version. In some embodiments, the rate matcher uses a first puncturing algorithm to generate both a first redundancy version and a third redundancy version, but allocates a different proportion of the systematic bits to these redundancy versions. In these embodiments, the second redundancy version may include only bits that were not transmitted in the first redundancy version.

Abstract: A hand-held printer that includes an inkjet array having a plurality of inkjets is disclosed. The hand-held printer may include an inkjet cap sized to cooperatively engage the inkjet array, wherein the inkjet cap is movable between and open position and a closed position, and a plurality of wipers carried by the inkjet cap, wherein each of the plurality of wipers is configured to engage one of the plurality of inkjets as the inkjet cap moves from the open position to the closed position; and wherein each of the plurality of wipers includes a gasket configured to form a seal adjacent to one of the plurality of inkjets.

Abstract: A cancellation system is disclosed for processing incoming and outgoing signals in a transform domain to create a cancellation signal for reducing or removing unwanted interference. Data is ordered based on Good-Thomas indexing into a two dimensional array in a buffer. The two dimensional array may have lr rows and lw columns. From the buffer, the columns of data undergo a Winograd small transform. The rows of data undergo a Cooley-Tukey operation to complete the transform operation into the frequency domain. Multipliers scale the transformed data to generate a cancellation signal in the frequency domain. Inverse (Cooley-Tukey) and Winograd transforms perform inverse processing on the cancellation signal to return the cancellation signal or data to the time domain. Re-ordering the data and combination of the cancellation signal or data with incoming or outgoing signals achieve interference cancellation.

Abstract: A network interface including a radio frequency (RF) system and a media access controller (MAC). The RF system wirelessly communicates with an access point (AP). The MAC includes client modules. A first client module transmits a first signal from a host to the AP via the RF system in accordance with a first wireless communication standard. A second client module transmits a second signal from the host to the AP via the RF system in accordance with a second wireless communication standard. The second client module determines a quality level of the second signal transmitted from the second client module to the AP, and based on the quality level of the second signal, hands off access to the RF system from the second client module to the first client module to allow the first client module to transmit the first signal to the AP via the RF system.

Abstract: A coexistent communication system of a first network device includes a remote network radio. The remote network radio has a remote transmission distance, operates based on remote network protocols, and communicates with a base station using a first communication link corresponding to a first frequency band. A local network radio has a local transmission distance and is collocated with the remote network radio. The local network radio operates based on local network protocols that are different than the remote network protocols and communicates with a second network device using a second communication link corresponding to a second frequency band. A control module at least one of schedules communication on the first communication link and the second communication link and adjusts a transmission parameter of one of the remote network radio and the local network radio. Transmission distance of the remote network radio is greater than transmission distance of the local network radio.
